hello there...i got this issue today. I can't login whatever i do all the FAQs in this forum. Installed new version of the client also didnt works. Here are the error code
"com.faforever.client.login.TokenRetrievalException: {"error":"invalid_grant","error_description":"The provided authorization grant (e.g., authorization code, resource owner credentials) or refresh token is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."}
at com.faforever.client.api.TokenRetriever.lambda$retrieveToken$1(TokenRetriever.java:111)"
so...whats happening? My laptop runs on windows 11, already giving permissions and whitelisted fafclient.
