Loginpate on iPad ist not working

Hallo,

when I click on my iPad on „Log in“ at the „https://cospaces.io/edu/“ site it goes to a site called „Did you get lost?“.
It was like this, when the App from CoSpaces was installed and it was like this after I removed it.

On the Windows-Laptop everything works.

Can anyone help me?

Thanks,
M. Döbele
