The TCP port of the HTTP server is privileged or already in use: (port = 8042)

Hi, I run into the above error message when I want to start an Orthanc Server in https mode. I had already contacted the author of Orthanc, and he could not reproduce this (with my config files and certificates) on Debian. So the assumption is that it is a distribution (Leap 15.3) specific issue. Log of the (manual )start as root using /usr/sbin/orthanc --verbose --trace-http --logfile=http_orthanc.log /etc/ orthanc/ https://paste.opensuse.org/92992870 What I tried: ss -tulpen does not show the port being used switch off apache (reverse proxy) switch off AppArmor Is there any openSUSE specific configuration that prevents using high ports?
