Optimization / Connection Url of server invalid

[desic]

Priority/Impact

Low (minor inconvenience)

Description

If the docker is not running and you try to connect via the wger mobile app you get the following error message. (maybe only if you already were connected via mobile app and server is down)

A simple "connection to the server url not possible" or "not found" would be much better

Server version

No response

Mobile app version

No response

mhh, if the connection is not possible you should indeed see a custom error message

Edit: when only the web container isn't running the reverse proxy will return html instead of json, but we should also check for that case and render the response

That's true but if I close the wger app on my android and reopen it I need to relogin with credentials because you get automatically logged out.

And then I get the mentioned error mesage
