Login button disabled

[fps]

I filled out all the required fields but the login button stays disabled (see screenshot below).

I followed the guide from my university here: https://www.uni-bielefeld.de/einrichtungen/bits/services/kuz/e-mail-und-kalender/anleitung/kalender-abonnieren-unter-android/index.xml

So I'm basically stuck at step 2 without any indication of what might be wrong. I'd be grateful for any hints :)

Hello,

I would suspect that there's some unwanted space, like [<space>]https:// in the URL, making it invalid.

Can you please verify that there are no unnecessary spaces surrounding the strings?

Hey, I tried twice yesterday and probable copied the space with it twice as well. Today it just worked - I did make sure to have no additional spaces though..

Thanks for the hint! That was probably it although I cannot confirm. The activity lifecycle was ended sometime so I couldn't recheck the string I had in there!
