[Feature Request] Changing URL

[Lucas van L]

It would be nice to change the URL of the server as my server has a new IP address which I cannot update in the app.
Changing the IP in the database only made the app crash for some reason.

I hope this feature can be added or explained how one can do this.

Thank you.
