Port Conflict on Raspberry PI with Kolibri

hello @Gibson , it will depend on the reference used exactly, there are several ways to do it, the easiest one https://kolibri.readthedocs.io/en/latest/install/raspberry_pi.html does not have a nginx captive portal so I am a bit lost.

If you did it using kolibri-server you can do dpkg-reconfigure kolibri-server and it will show you a list of ports to run kolibri and will update the configurations according to your selection.
