I have been trying for days to log in. No matter what I do, I keep getting could not connect to [server]. I tried for days and it didn’t work.
Then I realized. I have a password manager installed, and I let it pick its longest password length (100 characters). I reduced it to 32 characters, and my login immediately worked.
Lemmy itself supports huge passwords, but it seems as if mlem does not. I do not know how long your password can be before mlem pukes on its own shoes, but it’s somewhere between 32-100 haha.
I also had a problem where Mlem was failing to log in, but for me it’s that I was logging in with my email address. Once I switched to using my username, it worked fine.
