I have two new and recently updated nextcloud-installations on two different servers (both at german hoster domainfactory). Everything is working fine so far (only a little slow).
But the caldav isn’t working at all.
I neither can use it with iOS nor with Thunderbird/Lightning. I always get an error message (i tried literally every combination of server adresses and username/password).
Is there someone who get this up and running?
PS. On old owncloud installation the caldav works fine on the same server …
