Jetty request failed: null and SSL handshake failed

I am using the latest versions.

  • Openhab v3.0.2
  • Android App version v2.17.0

In the log, I periodically get the following warnings

These warnings seem to occur consistently when accessing OpenHAB from a mobile device (android) with a remote connection. In addition, the app quite regularly gives the following error

Not sure if this is related, but these errors seem to go in tandem.
I have seen various links on the jetty error, but mostly on older versions without a solution.

Suggestions?

Thanks, I guess that should address the issue on the app (SSL handshake failed).
It is also the cause for the jetty warnings?

No:

Thanks for the reference. At least I know the issue is still open.
