Summary of the issue you are facing:
I have the following error Message.
- Your web server is not yet properly set up to allow file synchronization, because the WebDAV interface seems to be broken. To allow this check to run you have to make sure that your Web server can connect to itself. Therefore it must be able to resolve and connect to at least one of its
trusted_domainsor theoverwrite.cli.url. This failure may be the result of a server-side DNS mismatch or outbound firewall rule.
I can connect via WebDAV with My IPad With the Nextcloud App for PC and Linux just on Android it does not work.
Neither the Google Play nor F-Droid Version work across diffrent Phones
It says Malformed Server Configuration
Steps to replicate it:
- Just Installed the Docker AIO Container in a NPM as Reverse Proxy in the nextcloud aio Docker Network
