The only game we have issue with is Stardew co-op. Other games, like Don't Starve Together and the Survivalists, as examples, give us no issue when playing together (regardless of who is hosting, when it requires that).
I can't tell you whether the Stardew co-op issue is limited to connecting to each other or just in general, because there's no-one else we play with, so we can't test that.
No, we're in entirely different households. The last time we successfully managed to play Stardew co-op was the same, so we can't figure out why it suddenly stopped working.
To summarize the issue, we receive the 'Connection failed' message every time the second player attempts to join a local CO-OP game (playing on one device) or a local CO-OP through Remote Play Together(playing with a second account). This is not an issue where both parties owns the game.
Here is a list of 'solution' we tried that DIDN'T help at all.
1) Guide from https://stardewguide.com/uncategorized/fixing-a-connection-failed-error-stardew-valley
a) reboot your game/client
b) restart both your device you are playing on and your networking equipment
c) turning it off and back on again
d) Steam client itself not being updated to its most current version
e) lack of signal strength from the user’s Wi-Fi or a communication issue between the
user’s device and the router
f) disabling your VPN
g) temporarily disable the applications or add exceptions for the game files that are
getting caught by your Antivirus software or Firewall
h) downloading and reinstalling Visual C++ Redistributable Packages for Visual Studio
2013
2) Guide from https://www.stardewvalley.net/multiplayer-troubleshooting-guide/
a) Check that Stardew Valley is up-to-date.
b) Hosting Player: Ensure the game is started in “Co-op” mode
c) Hosting Player: Check the number of Cabins built on the farm.
d) Ensure the game is started in “Co-op” mode
e) Desktop: Ensure that Steam/GOG Galaxy are running.
f) Desktop: Temporarily disable, or make exceptions for Stardew Valley (and Steam/GOG
Galaxy) on any active anti-virus software or firewalls.
g) Restart your device/router/modem.
h) Potential Steam username issue.
3) cabins already existed
4) same result with old and new farms
Furthermore, we've made an observed that this issue seems to only exist on my main device(PC) for unknown reasons. I tried hosting a game with my main device to at least two other devises, a low-end PC and a decade old laptop. The issue persists, no surprise there. But when I tried doing it the other way around, it worked normally. Running the game and starting local co-op through Remote Play Together on the low-end PC and the old laptop worked just fine. Remote Play Together worked perfectly even between the low-end PC and the old laptop.
I don't know what to make of this. It's frustrating to have this much trouble for a simple game.
I hope the developers would address this soon.
I just realized that this post is from 2021. I apologize for that.
If you have found the solution to this issue, please post it here.
Hi, no need to apologise! Your truly comprehensive list of attempted solutions is very helpful, and also matches with what we've also tried to no effect. Despite the thread being from 2021, we haven't managed to sort this out either.
Curiously, your comment about the PCs gives me pause--when my friend and I played on our long-standing farm, it was predominately on an older (laptop) of mine; it's since packed up, so I can't check, as you have, whether a different/older PC has the same issue. However, I did notice that this issue didn't start until we began trying to play when I'd moved on to my current PC.
I -would- speculate that it might be something as simple as versions of Windows (whether versions generally or update versions--I'm aware there was at least one update that caused games that were previously playable to no longer (in that case) boot at all, due to a checking system that was removed that these games needed to initially launch; my laptop never got this update), but I cannot definitely hold anything by it, as (see below): *
But to answer your question: I do not, unfortunately, have a solution. My friend and I have tried many times since to play Stardew together and have had the following results (note also, however, that our attempts to connect are through two separate computers in two different locations/households, and we're not using Remote Play, just in-game co-op):
- cannot connect at all when I am hosting our long-standing farm
- cannot connect when I make and host a new farm
- can, occasionally, connect on a new farm my friend made and hosted (can be reconnected to, if not reliably)
- said farm has issues with saving, however. Each in-game day is a lucky dip of whether it will save properly or just freeze
*Now, this would rule out the update theory because my friend uses the same version of Windows as me.
However, I think they're also using the same computer they had when we used to be able to connect without issue; I am not. This just lends further credibility to the possibility that it is something to do with--or perhaps more intrinsic to--the computer(s) in question; differing (or conflicting) hardware, drivers, updates, or some setting that isn't user-controlled, maybe--I can barely speculate.
I simply find it curious that the issue does not seem to be present on older/lower end devices. There must be a correlation somewhere, only it's hard to pinpoint the exact cause when PCs can themselves be so varied. Trying to narrow it down would probably require comparisons of hardware and software alike, and a larger sample size. And then it might not even BE something to do with that.
Unfortunately I don't have anything more concrete than that. I can't replicate or tell you exactly why we've been able to connect (if not reliably) only when my friend hosts; we don't know why that (somewhat) works ourselves. It's also not a fix; it's still hit-and-miss whether we can connect, we have the save issue etc. It's troublesome enough that for the most part we've simply given up trying to play Stardew together, which is honestly an absolute shame for such a fun game.
If I get any more information or manage to figure out a more definite 'this is why', I'll be sure to get back to you here (and my own apologies for my extremely lengthy reply). Otherwise, if anyone wants to add to this thread, please do.
I have NOT allowed my laptop to update for that reason. While my friend took her pc in to her computer guy (because she was having a minor problem) and he updated her pc to windows 11 , and as a result she could not play SDV AT ALL. It took her weeks to get him to change it back to windows 10.
You also didnt mention of you are strictly vanilla version or if you have mods. Are you 32 bit version or 64 bit version?? i think both people trying to connect need to be on the same version of the game.
I played (with mods) with my friend while in 32 bit version just fine, but when I updated to the 64bit version of the game, she could no longer connect to my farms, (she was still 32bit) but I could connect to her farms. New can go to old, but old cant go to new. At least that is my take on the problem.
Could it be your older pc's are all running the 32bit version still, while you updated the game on the newer pc and it is running 64 bit version??? Did you try switching the new pc to run the 32 bit version under the Beta tab??
I wouldn't touch Win11 with a barge pole; my friend and I both have Win10 and I have no intention of ever 'upgrading'. The laptop I was using before (the one that currently doesn't work) was also running Win10; however, this was before some major updates to the Win10 version, which is why I suspect that one of those (a Win10 update my laptop didn't get but this computer did) could be part of the problem, as those updates HAVE caused issues with other games for me.
Good point, let me address those in turn:
At present I have no mods installed. Ironically I did use mods on my old laptop (a simple fishing mod and portrait swap that I did manually); at some point I think I was even launching the game through SMAPI. They never caused any problems and I recall testing them with my friend to make sure. Regardless, mod conflicts/co-op incompatibility was one of the first things we checked, and to my knowledge we're both using the vanilla version atm.
Interesting. I'm using a 64bit PC and my old laptop was 64bit as well. To my knowledge my friend is also 64bit. I'm sure that was also something we checked (though I will double-check; if I don't edit this, it's 64bit), and as Stardew apparently now runs by default on 64bit and we're both using the latest Stardew version, I'm guessing the little warning that apparently comes up if you're not 64bit would've notified her.
However, I can't remember whether we tried running Stardew in the 32bit compatibility mode, so thank you for pointing that out, we'll try it.
(This is where I think the questions are directed at the other user; hopefully they'll see your questions and can comment on which game version their older PCs are running, etc)
I think part of the problem isolating the issue on my end is that my laptop breaking down and several Stardew updates happened at about the same time.
Actually, after some investigation, I've found that we played 1.4 (with the 14 heart/post-marriage events) at the end of Nov 2019 with no issues. Following this, Stardew updated three more times in that Dec, where we didn't play, and then my laptop broke. By the time we tried to play again (now on my replacement computer) there'd been at least another two updates, and now we had connection problems.
Either something was kicked over in one of those five updates, or the changing of computer caused the problem; I can't work out which (though as I'm not the only one with these problems, I've been more inclined to think it's something from one of the updates; I just can't be sure that it's not something as simple as a framework this computer is missing that the previous had, or vice versa, or some Win10 update that messed something up in the interim).
Regardless, as you can see by this thread, the problem persisted (and still persists). We occasionally tried to play co-op again. notably after updates (in case it fixed anything), but by the point of me starting this thread we'd all but given up. Then we (somehow, somewhat) managed to connect with my friend hosting (which we had tried before to no avail, and I still don't know why or how it 'worked').
However, I still can't host (at least with my friend, I haven't been able to check with anyone else), and the connection is... iffy at best, so I don't consider the matter at all resolved.
I don't know if any of this helped at all, but I'll try the beta thing when we're able and update here with results.
Note: we were sitting in the same room, on the same wifi.
Mind you we both have mods in the game and I know I have more mods then she does, and several mods have said they dont work in co-op mode.
But it was interesting that HER game crashed first when I tried to join her farm that we had been playing together several months ago.
Its also interesting that Steam did a major update today, and included a fix to library & games crashing, Don't know if that will make playing co-op easier, since we are linked thru friendship list on steam to play co-op.
- we're both playing on 64bit machines, confirmed
- we both attempted to connect using the 32bit compatibility mode: my friend's game wouldn't even boot in that mode, but mine would
- I attempted to host using the Comp mode, while my friend reverted to 64bit. Surprising both of us, it worked! We didn't even have save problems.
- I attempted to host a different farm: it also worked
- My friend attempted to host me, same set-up: also worked!
- I then reverted to 64bit as well. Nobody was using Comp mode. I attempted to host.... it worked.
So at first I thought we had a workaround: me on Comp mode, my friend not. But it turns out that it just works now. Whether we somehow fixed something /through/ the switching of modes, or whether Stardew itself fixed the problem without us noticing prior to this, or whether it was a Steam update that fixed it... it now, seemingly, works. We can connect farms.
Additional notes:
My friend IS using mods; I'm not. We're both still connecting remotely over wi-fi with our own separate game copies. Neither of us did anything differently apart from attempting/initially using Comp mode.
I think this matter is still worth investigating further because without knowing what the cause was, I do believe it could reoccur (and it bugs me endlessly that I don't know the exact cause); and it's obviously affecting a lot of people still, yourselves included.
I wish I could give a more definitive answer on why it's suddenly working again for us (after literally years of it not). As it is, if there's any additional information etc, please do keep adding it here.
Ditto here :(
We've tried what feels like every trick in the book. I am so frigging frustrated..... Bought this game to play with my sibling, it was all good for 2 weeks of playing just about daily and then yesterday connection failed. We've tried for hours to fix it.
