Hello,

I recently installed NextCloud v.15.0.5 on a spare Ubuntu 18.04 LTS server in a dockerised environment by using the docker-compose (apache) file that was provided at the official [docker repo](https://github.com/nextcloud/docker) for NextCloud over at Github.

The web UI is made accessible through a reverse nginx proxy that maps the exposed docker port to a subdomain with format `https://cloud.domain.tld`

Connecting, downloading and uploading files through the web UI itself works fine, however, I’m met with “No internet connection” after logging into my Nextcloud server using the android application.

### Additional information:

- Android Version: 9
- Nextcloud Android Version: 3.5.0

After searching for issues similar to mine, I did find [this github issue](https://github.com/nextcloud/android/issues/3518) with exactly the same problem that I encountered. Despite that, I’m unable to fix the issue on my end.

Any help would be greatly appreciated and I’ll do my best to provide additional information, if needed.

Thank you.
