JVB Port 443


we are trying to use JVB on Port 443 (< 1024). We have tried following options:
Running JVB on port 4443 and redirecting 443 to 4443 via NAT: then we have this issue in Chrome https://github.com/jitsi/jitsi-meet/issues/6327

When we try to start jvb within a container listening directly on port 443 we always get this exception:
Failed to initialize TCP harvester on port 443

We already tried: JVB: How to listen to port 443
