Jitsi-meet matrix-synapse and openvpn on one host cannot connet to jitsi web interface

Hi fellows,

I need your help after days of searching I didn’t found a solution yet.

The situation I have openvpn running as a template on port 943
nginx on 443
and matrix-synapse on ports 8008 and 8448

in the meet.domain.de.conf I tried forwarding ports like that
org.jitsi.videobridge.TCP_HARVESTER_PORT=65443
org.jitsi.videobridge.SINGLE_PORT_HARVESTER_PORT=65000

and
org.jitsi.videobridge.TCP_HARVESTER_MAPPED_PORT=443
org.jitsi.videobridge.TCP_HARVESTER_PORT=4443

in /etc/jitsi/videobridge/sip-communicator.properties
both didn 't work whatever I try https://meet.domain.de directs me to the openvpn config page

How can I fix that?

Many thanks in advance

Uli
