Our solution for DCs problem

[AISguy]

We tested playing just without IPv6 (with and without VPN) and then through different routers through Ethernet with disabled/enabled IPv6 (without VPN) - my friend went to the other room with other router (and other intranet IP).
All games still were with critical DCs, even the one that was 1h40min long.
There are still some configurations to test (in other room with VPN and enabled/disabled IPv6), but the behavior before this was always the same - a random DC during the game, so I think the problem might be somewhere else.
Logs and replays of today's games are attached.

Currently, I see several issues that can cause such behavior (If there's something else, please add):
1. Provider issues. During testing, the provider was always the same.
2. One of our computers messes things up. Insufficient resources, for example. However, we were able to handle 2000 units during our previous testing without DCs.

Except configurations, I think there are several things to try (If there's something else, please add):
1. Different computers. For example, install FAF on different computers and try to run a match with the same provider.
We can try to find someone to try, but it will take time.
2. Different provider with the same or different computers.
Providers cost money, and we have no other Ethernet providers except the one that we're using now. Only the 3G/4G ones.

Are you sure this is even a connectivity issue? Maybe you guys have different/corrupted game files. Clean install on both machines with no mods. Also no campaign - I would just play vanilla games until this is resolved.

Each of you should try and play a game against a different normal random person. To try and work out which one of you is unstable.

Maybe you could try launching games through vanilla steam lobby, and trying to launch through FAF lobby.

Anihilnine, thank you for your suggestions! We will definitely try these cases.
We've just cleared cache and everything possible through FAF, uninstalled all versions of FA from our computers, installed Steam version ... and still got DC after 1h15min of the campaign mission.

By the way, Is there some way to log the process more thoroughly, so we could understand what exactly triggers the DC?

AISguy!

Wow nice presentation of your logs. That worth a like from me!

Well, this is my RAW written checklist. ToDo's are at the end.
The other stuff is just info


Game.log:

Player 1 AISguy
---------------
steam game
Got disconnect message from other player

Player 2 Quarrel
----------------
steam game
Got disconnect message from other player
Double installation of mods in different directories.
1st Mod Dir: 'c:\users\misto\documents\my games\gas powered games\supreme commander forged alliance\mods'
2nd Mod Dir: 'c:\programdata\faforever\user\my games\gas powered games\supreme commander forged alliance\mods'
Double mods:
exmex
t2_t3_storage_faf
t3engstationsfaf


Both games got disconnets message, no PC crashed.
Problem is outside Game


forever.log:

Player 1 AISguy
---------------
UnicodeEncodeError: 'ascii' codec can't encode characters in position 9-15: ordinal not in range(128)
Username 'ƒмитрий2' has a not decodeable ascii characters (can only changed with new windows installation!!!)
several connection erros to IRC
UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 6674: character maps to <undefined>
code 0x98 = 'И'

Player 2 Quarrel
----------------
perfect log.
UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 6836: character maps to <undefined>
code 0x98 = 'И'

Several errors related to decode unicode chars (russian language?)
Game disconnects are shown inside the log from the client. No errors related to disconnects.

------------------------------------------------------------------------------------------------------------

Both PC are good.
Both clients are good
Some errors related to russian language (not disconnect related)
Error is outside software range. Check hardware.


------------------------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------------------------

ToDo:

Hardwaretest local at home. (network cards and router):

Please make a shorcut from the SupCom exe and start the game with the shortcut.

Code: Select all

C:\ProgramData\FAForever\bin\ForgedAlliance.exe

Start a (local) Multiplayer game from the ingame menu and test stability.

------------------------------------------------------------------------------------------------------------

Hardware/connection test outside (Router connection to the internet)

Open a DOS window and type:

Code: Select all

ping -t http://www.google.com

This will continuous send a ping to google.com. There you can see if your connection will get slow or disconnect.
Start the FAF client and make a game.

[AISguy]

Thank you, Uveso!
We'll do it.

Currently, we tried a game versus two other people. First and fatal DC between me and my friend happened after several minutes.
This time we played through the same router.
There were no DCs between me or my friend and someone else.

[Uveso]

Well, the log from player 2 is perfect, i see only connection issues and errors in the client log from player 1

But i don't know if those errors are from the russian directory name (Дмитрий2 / Dmitry2) or from the internetconnection.

Can't wait for the local network play result

[AISguy]

Ok, we played a local game, but we forgot to enable FAF, so, unfortunately, no logs this time.

We played a skirmish without DCs with 2 bots on a 20x20 map.
Based on ping, the network had the same behavior as usual, namely constantly good pings with 1 out of 500 packets dropped almost regularly due to timeout.
