could someone please help me with a problem with the identifier links?

We just upgraded from 1.7 version Dspace to 4.1.
In the old one we had identifiers like this:

Now they include also the ui name in the link:

Tried every combination, set the handle canonical prefix, even deleted the /jspui part from the base.url but nothing worked.

+1  The OAI page works when using
but every link on that page points to the inner network ip not the hostname. Tried modifying the oai.cfg, but nothing changed.
Any ideas?
Can it be possible that Dspace does not use the settings from dspace.cfg but from somewhere else?

Thank you very much for your help!
