"Failed to Join Requested Game" and "Fatal Error", A Tragic Story of Four Friends.

[RinRin]

Me and my three other friends bought the game a week ago. One of our friend had problems joining our Co-op server for no absolute reason. Other than that other two kept getting random crashes and fatal errors with no comprehensible logs about them. I, also, had fatal errors and random crashes while loading, etc. We ruled that it was the mods and disabled them entirely. The first friend I mentioned still couldn't join our game even without mods or anything. After a while we managed to solve his problem, but he had to use a VPN to play with us. Interestingly, we could join his server without him using anything like a god forbidden free to use VPN. Later we managed to get the mods working as well.
We played, we built, we slayed, we enslaved, and we enjoyed the game. -Only for a couple of hours.- Then we had a "Fatal Error", which made us quit the damn game for that night.
After almost a week, non of could connect to each others Co-op. No matter what we do and what we try, we cannot connect. Some of us even re-downloaded this cursed game, still nothing. We tried basically everything that comes to mind. Validating game files, re-downloading the game, installing/uninstalling battleye, clearing steam download cache, emptying the workshop file and re-installing mods, trying without any mods, and yet "Failed to Join Requested Game" had emerged victorious.

WE. CANNOT. PLAY. THE. GAME. WE. ENJOYED.

Thus, I walked upon this cursed forum of this cursed game. It is help I seek. WE NEED HELP.

Problems:
"Failed to Join Requested Game"
Random Crashes
Connection Issues
Major Connection Issue, where we can join that one friends game, but he had to use a VPN to join us.

Request:
Help a group of friends enjoy the game without, atleast, any connection issues.

Thank you for your attention.

Yours sincerely, MuX.

PS. Excuse my language related mistakes. I haven't slept for 3 days, for I had assignments and exams.

one item you don't mention is battleeye, do you have it installed?

[RinRin]

I mentioned it on the last paragraph. We played Coop without battleye installed for around 12 hours, I think. I have been trying out stuff. I installed battleye and tried joining an official server, which worked. But, still neither I, nor my friend join each others Coop.

Have you tried to setup a local server instead of using the co-op function? The dedicated server app may be downloaded from the official forums.

[RinRin]

Unfortunately, due to my ISP's adoption of CGNat recently, I cannot open/forward ports. We may try using Radmin or Hamachi or smth like that, but we really don't want to mess with a dedicated server. It's going to be our last resort, I suppose. I really don't understand why we have such issues. Coop worked for hours with a few hick ups here and there. Anyways, I thank you both for your replies and ideas.

[Multigun]

Ugh, not able to mess with your router ports. Sounds not fun.

Surprised you got co-op working at all for the time that you did.

[RinRin]

It sucks. You can't even open a port for basic stuff like FTP. And, when someone gets banned from a site in the same CGN, you also get banned. I'll be filing a complaint, if they keep this BS going for another month.

It worked well. We had to disable/reanable mods each time someone wanted to join so that nobody get a random "Fatal Error" every 10 minutes. Other guy managed to join via VPN, as I mentioned. So far I haven't found any way to fix the "Failed to Join Requested Game".

[RinRin]

Alright, fellas. We managed the fix our problems.

For the "Failed to Join Requested Game" part on my side;
1. Backup \\SteamLibrary\steamapps\common\Conan Exiles\ConanSandbox\Saved
2. Delete \\SteamLibrary\steamapps\common\Conan Exiles\ConanSandbox\Saved
-This will delete all of your local saves and configs.
3. Launch the game and create a new Coop game.
4. Have a friend handy to try things out.
-If they can join and play Coop with you.
5. Remove .db files in \\Conan Exiles\ConanSandbox\Saved
6. Copy .db files (game.db, game_build.db, game_upgrade_tags.db, etc.) from your backed up Saved file to \\Conan Exiles\ConanSandbox\Saved.
-This should replace your previous local saves.Redo your server settings if necessary.
7. Try if it worked for you and your friend.

For the guy with the VPN;
He apparently joined Beta thinking it would fix his connection problems. Leaving Beta fixed the "Failed to Join Requested Game" error on his side. After some tinkering and troubleshooting, we realised he had a DNS issue on this ISPs side. We knew it was his ISP, so it seemed using a free to use VPN would be a solution at first. It was a terrible solution, 500+ ping, random disconnects, etc. To mitigate this problem, we used DNSCrypt Proxy (found on GitHub). GoodByeDPI_GUI by cheytacllc (GitHub) to be exact. He had lower than 100 ping and basically fixed the connection problems caused by his terrible DNS resolver provided by his ISP.

Hope this would be useful. (=

[RinRin]

Neither I do, but we haven't had any issues so far.
