I was playing Avowed through Battle.Net for the last couple of days without any issues. Tonight when I wanted to play, when the game loads up after shader compilation and intro videos and prompts to press any key. I get the "Error Login failed" message. I do not know what to do to fix. I have tried restarting the game, restarting Battle.Net, logging out of Battle.Net, deleting cache, verifying game files, restarting the computer. Resetting all kinds of internet connection related stuff, restarting XBox game services, logging out of xbox, logging back in. Are the Xbox cloud services down?

I have the same issue. I most recently played last weekend without any issues.

I fided it by manually logging out of Battle.Net and back again. I presume it is a Battle.Net problem, as they cannot figure out how to reconnect if you lose internet for a moment.

I did some more testing and I believe I’ve resolved the issue. I installed the game from Battle.net but I launch it from Steam (as a non-Steam game) so I can use their controller input driver for my PS5 controller. Apparently if I have the Battle.net client running while launching the game from Steam this error occurs. If I exit Battle.net then launch the game from Steam there is no error.
