I can't join friends game when I'm on my home wifi, bu I can, when I'm on my phone hotspot.

[Malkosvaidis]

I have a problem with my network. I can't join to my friend and he can't join me. This isn't on all games. CS:GO, for example - works just fine, but smaller games like snowrunner or overcoocked 2 doesn't work. However, if I connect to my mobile hotspot. (Different service provider) It works just fine. In both ways I'm using a 4G+ internet (that comes from sim card:D). I think something is wrong with my router settings. Have anyone got this problem too and do you have any Ideas how to fix this, because it's driving me crazy. If you need any information - feel free to ask.

So your home Wifi is using a mobile 4G connection and not a cable?
That smells like a latency problem, but could also be your router... or 100 other problems (Antivirus, Firewall Settings, Bluetooth sending on 2.4Ghz interfering your Wifi (Controllers use Bluetooth), ...)

This will be kinda tricky. We have to find the IP and possibly the port you are trying to connect to.

Open your Windows cmd terminal (Windows Key + R, type cmd, Enter)

With the command

netstat 

you can see all your connections.
Try to connect to a friends game while running the command and look what changes.

Copy the IP and run

ping your.copied.ip.here 

(this will measure your latency) and look at the results. You want to have at least about 100ms. Everything higher could be a problem.

Then run

telnet your.copied.ip.here port

(this will tell you whether there are port problems)

Hey, It's definitely not a latency problem. It could be something with ports or a nat type maybe, but I'm pretty sure, that my nat is open (did some youtube solutions). the problem is somewhere in the router or maybe even a pc. I called my service provider and they said, that nothing is blocked from their side. also, just powered on my Need For Speed game with same friend and everything worked fine. Tried Overcoocked 2 again, and I get and error called "GameLift - eNoHostConnection." The friend has the same error, when he tries to connect to me. Tried your solutions. Although I had no difference when joining a game, after starting it something popped up. I don't know how much I can show it to you over here, but at third column there was a bunch of TIME_WAIT readings. So I assume, that It could be something with ports right?

[Arg0n]

Mine isn't a solution, but a way to figure out what might be wrong ^^
Ya, that should be an IP with a PORT behind it. E.g 123.123.123.123:4567 on the line
You can ignore 127.0.0.1 (thats your machine) and anything with 192.168.xxx.xxx (thats, your local network e.g. where your router is in)

This would be the IP: 123.123.123.123
And this the PORT: 4567

With the "telnet" command, you can check whether the port is open and responding to smth.

telnet 123.123.123.123 4567

When "telnet" isn't available check https://social.technet.microsoft.com/wiki/contents/articles/38433.windows-10-enabling-telnet-client.aspx on how to activate it.


If you have the IP, you can also check it with "tracert"

tracert 123.123.123.123

This will show you the "route" your connection is taking trying to find the IP. There you should™ also see your providers IP or DOMAIN in the list and whether it ends there.

Hi again. I found out, that Overcooked is using p2p connection type. I tried to do a p2p port test and all of them vere "timed out", Could it be, that my router somehow blocks p2p connections?

[Arg0n]

Yes it's most likely your router blocking the needed port. P2P can use a lot of ports. It depends on the game. You can enable UPnP[en.wikipedia.org] on your router or enable the port you are needing for each game manually.

sounds like router is not first jump on own lan netwrok but connect to other , sense it work with own hotspot direct connected. and you router connect to other own gateway router. ( if so then you have made wrong configuration ) and not sure steam will be bother with advance setup with 2 routers. ( can say you dont have standard standalone rounter connect to ISP directly if i ID this correctly i have no clue on setup, just that it sounds its that. ) after read your diffrent setup possible issue.

[Iceira]

just so you get it, 2 router is seen as business plan and configuration, privat user normaly forget what has been made and screw things up late, you need to be skilled enough or educate in this or master it. ( i cant say its that but just a friendly warning, why you have issue with it if im right in it. ) and why i wont explan this better, its advance network and out of most steam user graps and maybe best kept that way. )

problem here is , do steam want to be flooded with user that dont understand advance network, i doubt it.

UPnP is enabled, but it doesn't fix the problem. I guess I'll try to forwad the ports...

Btw, I'm launching game from Epic games. I'm just searching for help here...

I didn't really understand what were you trying to say... My router was bought for personal use and was always used like that. it's a common router, that many people use.. My router - Huawei E5186

I guess he's assuming you have a router connected to another router, which then connects to the internet. And if so that there might be something wrong with the router to router connection. But I don't thing you have such a setup :x

Was UPnP enabled all the time? Because the check via https://www.whatsmyip.org/port-scanner/p2p will fail regardless. UPnP is there so a program or game can open the needed ports by itself. So you would have to start the game and try to connect to your friend to find out whether UPnP does it's magic or not =)

[Iceira]

also talk with own ISP what if there is a local isp that dont route things in, require public ip-adr. ( such company is there today ) all privat or host games is seen as require public ip-adr so things get inside. ( this is same clue ) same problem local isp network to yours local network ( same problem )

UPnP was on all the time, but it doesn't work. I tried to download hamachi, and the connection worked. my friend were able to join my game, but now the hamachi struggles on my side too. I can't normally connect to my friends ip. it just shows a blue circle and when I trie to ping my friends ip it just says "timed out", but when my friend pings my ip, hamachi whos a connection, but it has a huge ping (180ms). any ideas?

[Iceira]

Can you bypass own router if wallplug is rj-45 then test with spare laptop to ruleout own router firewall or pc firewall is doing it ( still dont rulreout isp firewall or it never being routed in )

Some ( ISP VIP portal )other have a most have public ip-adr, or you cant make service from inside lan ) you can make the service, but none from outside can join it. ( same as not route inside, a protected network )

I think it's NAT type issue or your global IP has blocked.

NAT type
It's about how your PC is connected to internet.

In general:
OK: Internet - modem - PC
OK: Internet - modem - router - PC
NG: Internet - modem - router - router - PC

I found following guide has good info.


Global IP address

It's IP address to your computer / network from internet side.

In some case, it may be blocked by certain services.
I have got blocked some phone game and Playstation network a couple times.

Following is steps to change your global IP address
1) Check current global IP address
ex) http://www.myglobalip.com/
2) Go to your network router setting and change MAC address
3) Restart modem and router (Turn off both. Turn on router. Wait 5min and turn on modem.)
4) Check global IP address again using 1)'s site

There might be a problem with my NAT type. On router, there are two options for NAT settings: Cone and symmetric. Mine is set to Cone, but when I check my NAT type, it says "symmetric" tried to mess between "Cone" and "Symmectric" settings, but as I check it always shows "symmectric". I used this site - https://clients.dh2i.com/NatTest/
Is there a way, to somehow change NAT type?
