I have just migrated my square white Hue bridge to a new square black Hue Bridge Pro. I used the migration feature in the Hue app (replace an existing Bridge). Hoping I could retain my openhab setup. All the lights and setup have been transferred to the new Hue Bridge Pro.
I changed the ip-address in the Hue API v2 Bridge, I also created a new Application key, using the api debug tool of the bridge directly ( needed to press the button 
).
Using the ip-address and application-key, from the command line of my openhab system this works just fine,

If I use the same ip-address and applicationkey in openhab I get the following error:
COMMUNICATION_ERROR
An unexpected exception occurred: java.util.concurrent.ExecutionException: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
This is the definition of the Bridge:

Forgot to mention: same issue in Openhab4, upgrade to OH5 did not change anything
Has anyone connected the new Hue Bridge Pro to openhab yet?
I was more like observing how others have a go with it and looking if the most crucial features don’t break.
