Problem connecting to openHab 5.0.0

[kprueckl]

I've just upgraded my openHAB installation from 4.3.5 to the stable 5.0.0 release and since that the Windows App is - in contrast to the Android app - not able to connect anymore.

The log says:

In case it matters, openHAB is running on a Windows 11 with Eclipse Temurin - also updated from OpenJDK17U-jre_x64_windows_hotspot_17.0.15_6 to OpenJDK21U-jre_x64_windows_hotspot_21.0.8_9

Thx

Found a solution by adding V5 to src/openHAB.Core/Model/OpenHabVersion.cs and to the check in ‎src/openHAB.Core/SDK/OpenHABClient.cs

Looks like this in my fork: 62ca231 but I didn't manage to create just the PR of this change. Will try another time.
