Can't log in anymore even with the password that worked for me (demo)

On this page

I was able to log in but now I can’t… it says “We have detected multiple invalid login attempts from your IP. Therefore your next login is throttled up to 30 seconds.”

I’ve waited more than 30sec, and refreshed the screen. But still no luck it still says that.

When I click log in it says “Logging in…” it still says “We have detected multiple invalid login attempts from your IP. Therefore your next login is throttled up to 30 seconds.” while it says “Logging in…”

I don’t know if that is because the demo account was only 60min and maybe I have been fiddling with these things for more than an hour. I was able to log in with the password “demo” a short time ago. And it showed an online interface with files. But I can’t get that now.

get a new ip… and try it again.
these demo-machines are working for 60 min, only afaik.
