Android: Graphs not showing when connecting through myopenHAB

I frankly do not know since when this problem exists but I am having the problem that on Android, when connecting to OH remotely through myopenHAB, the app does not show any charts. The respective screen just stays blank. Similar issues seem to have existed some years ago but I am facing this issue even with the latest release candidate 5.2.0.RC2. Is this a known problem?

Is this an “Analyze” or “Analyze All” chart or a chart page you’ve set up? I don’t have any chart pages myself but I can analyze to generate the charts and they seem to work in the Android app over the remote connection.

Yes these are “Analyze” charts. The weirdest thing just happened. On the same server, in another docker container, I am running also evcc, which uses a different port (7070). I just thought that to debug this I would stop that container - and that made the problem go away. Now I have even evcc running again and the graphs render okay. I cannot quite explain this but apparently there must have been some glitch. So never mind.
