--- Comment #4 from Dmitry dz64@protonmail.com --- This bug is still present in wine 3.13 and latest game client. It is possible to enable some network debug options in the game by following this guide: https://support.frontier.co.uk/kb/faq.php?id=343
By doing so, I've managed to get a detailed networking log: Webserver request: https://api.orerve.net:443/2.0/elite/user/login?B9cWZt... Plaintext error response: {"errorCode":272,"status":400,"message":"CRC Failed"}
Looks like this CRC Error is the one that appears in game ui. The game tries to access some kind of web-service and gets code 400. I'm not sure but I think 400 stands for malformed request. Maybe the game sends some malformed data to the server?
I've made a detailed debug trace of this issue, but it is too big to attach here. I've cut a part of the trace where api.orerve.net was mentioned. Ignore vulkan calls (i've used DXVK).
