The file openhab.liste is being ignored. That one is not in use and not causing your problem.

This means repositories are hosted in a different place.
Search for the SSL error message on the forum page or by using google and dong a site search only. This should come up with e.g. this thread: [SOLVED] OH2 & IHC and Java 1.8 - #6 by pauli_anttila
That proposed solution might not work as it is related to Java 8 and not Java 11 that is being used for OH3. I remember that also others have the same problem. So you may search for the other threads.
