I have to go through the “forgot password” procedure everrytime I’m relogging, i. e. after deleting the lemmy.world site data in my browser.
I can use (enter and verify) the same password without problems, but a normal login is curently not possible.
Update: I was able to login now. Fingers crossed.
It appears to be working now … did not change anything on my side … it just suddenly worked. … but everything is so painfully slow … and I also had at least one case where I was automatically logged out again after about 2 minutes …
