Symptoms

The game launches and loads with no issues, but displays "Unable to Sign In" error message when attempting to connect to Planetary Annihilation (PA) servers. Without compatibility support, the game launches with no connection error message, but the screen is "frozen" from user interaction, when in actuality it is suffering some sort of heavy lag response when clicking in and out of the game during Windowed Mode.

This next portion is not covered in the log, but from personal experience prior to the latest proton versions 6 and up.
If the Multiplayer portion is ignored, Single Player seems to produce odd results, such as the Campaign fights unable to "close out" properly after a match has been won, with the game unable to move on to the next part of the Campaign conquest missions. Gameplay works as expected from Windows, but the game seems to "hiccup" at times by either freeze-crashing or simply closing out of the game entirely.

I have yet to see if the Single Player portion works fully, as my main concern is to see whether the Multiplayer portion can be fixed or not.

Reproduction

Have tried launching the game as is, with little success. Then used the following launch options without Compatibility support:

• SSL_CERT_FILE=/etc/ssl/certs/ca-bundle.crt
• PROTON_USE_WINED3D=1
• PROTON_LOG=1 %command%
• --coherent-options="--renderer-process-limit=1"

Launch options were able to provide at least the game's opening cutscene to display properly, but interaction with the menu was "frozen", as described earlier.

Kept the launch options as is, while implementing the latest Proton version, Experimental, and older versions. Cutscene is bypassed, menu is useable, but a connection error is produced each time.

I welcome all troubleshooting suggestions, even basic ones that I may have overlooked or not tried at all.

Start by reviewing steam-386070.log alongside the reported Proton versions, system information, and launch options. Reproduce the multiplayer sign-in failure and menu interaction behavior for Planetary Annihilation: TITANS; done means identifying a reproducible compatibility cause and documenting or validating a fix.
