My desktop browser (Firefox and Chrome) on Linux just shows me a perpetual spinner icon when I click login. I had the same problem when I tried to sign up. My current work around is to access Lemmy on mobile only.
I’m not a fan of infinite spinners. ♾️
I’ve noticed something interesting. My account was created on my laptop. Logging in there is fine. From the phone, with the spell checker on, the phone brings up my username. If I click on it, it enters my username into the username box, BUT WITH AN EXTRA TRAILING SPACE. I’ll get an infinite spin if I use it as is, but can log in if I remove the trailing space first.
Thanks for your comment. You are absolutely correct I was using bad credentials. 😳
