update: now I cannot enter by webdav either. It now sends a 'http' service unavailable message :( Did a scan of my network with Zenmap and eveyrthing looks like it should work fine:

PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http
443/tcp open https

This looks more like a setup issue. For ssh we can't do anything as this is completely unrelated software. And the login needs to give you some hints (like wrong password or internal server error). I would say this is better suited to be asked in the forums to resolve the setup problems first: https://help.nextcloud.com
