Hey there! We're sorry this isn't working for you. Just to be clear, you should be typing "lemm.ee" in the "Instance" field and "chimera" in the "username" field.
If that doesn't work, there's unfortunately something wrong with our login system. I'm currently unable to find the root cause - I've tried creating an account on lemm.ee
, and am able to login without any problems. I've created an issue on our GitHub repository here and will let you know if we make any progress.
