Can´t create new account with the nextcloud app - Macbook


I have the following problem. I want to create a new account in the nextcloud app so I can connect to my cloud. The cloud is running well. I can connect via browser and via iPhone/iPad as well.

In the first step I have to enter my server address.
But than I get the following massage:

secure connection to the server address failed. How do you want to continue?

  • choose another URL
  • try http
  • configure TLS Certificate

-> http does not work.
-> another URL does not make sense

Operating system and version _(macOS Hight Sierra 10.13)
Web Hoster: webgo
SSL Certificate: Lets Encrypt

Thanks a lot
