Openhab 3 Docker migration to new host: No values on pages Chrome

I run Openhab on docker with a external database (JDBC) in another container. This works well.

Now I had to migrate openhab and the db to another docker host. (both debian VMs)

The migration worked and openhab stared as expected. Also all things are online. On some pages I displayed some cells with graphs and the value (standard openhab cell).

As I look into the graphs the recording of values works.

But the only problem: All values in the cells are not displayed anymore, but only in Google Chrome (Firefox works).
I already deleted the cache and all browser data.

Does anybody know where the problem can be?

Ok… Just solved the problem.
There was an issue with my ssl certificat.
