Hi,
Same problem here.
https://ocloud.de/product/ocloud.html
Galaxy S8 actual Enpass-Version from play store.
The address works fine in chrome browser, also in iOS and Windows 10 no problem with Enpass on this server.

Update:
It is definitely a problem no common problem. The reason must be by the configuration of ocloud.de . I have tested it with another provider (wolkensicher.de) with no problems.
I opened a ticket by ocloud.de.
