Me too; I opened a ticket with GOG support and did all the following actions, no success
-------------------------------------------
Many thanks for sending us the requested logs.
After going through them, I have managed to find the following:
2024-03-14 18:47:40.926 [Error][ (0)] [TID 30044][galaxy_client]: Failed to retrieve authData for platform epic. Reason: UnknownError, Error Error Message: Unexpected status in external accounts response [id: 724, content: , code: 400 - Bad Request]. (HTTP 400 - Bad Request)
The error code 400 tells us that the request to retreive the user data could not be completed, because the server cannot or will not process the request due to something that is perceived to be an error (for example, malformed request syntax, invalid request message framing, or incorrect request routing).
With this type of error please try the following workarounds:
1. Please add the following files to both your antivirus and firewall trusted/exception list:
C:\Program Files (x86)\GOG GALAXY\GalaxyClient.exe
C:\Program Files (x86)\GOG GALAXY\GalaxyClientService.exe
C:\ProgramData\GOG.com\Galaxy\redists\GalaxyCommunication.exe
C:\ProgramData\GOG.com\Galaxy\redists\GalaxyUpdater.exe
Make sure to restart GOG GALAXY after following above.
2. If you have already whitelisted GOG GALAXY files (it's important as simply disabling antivirus/firewall will not be enough, some processes may till be running in the background), some Users reported that having the "Scan secure connection" enabled in their security software was causing this issue, this option can also be called scan SSL/TLS connections - please make sure that it is disabled.
If that doesn't help, please follow the instruction below to reset network adapter's software to default:
1) Click on the Search Icon in the start menu and type CMD
2) Launch the Command Prompt by right-clicking and selecting "Run as Administrator".
3) Type “netsh winsock reset” and hit Enter.
4) Once it's completed you should see a message "Winsock reset completed successfully".
5) Restart your PC
