Problem
For quite some time now, I can’t access from my Gmail account specifically. Other E-Mail proverders work just fine but it always throws an error about how it wasn’t able to sync Mailspring with my Gmail account. Re-connecting the account doesn’t do anything. The only hints I can give is this error log (personal email redacted:
