ioBroker.admin: port 443 already in use (on another IP adress...)

You can set the Admin Adapter to a certain IP, but it doesn’t seem to check if the port is free on this IP, but if any IP is using port 443.

The admin instance is bound to 10.0.0.10 and there is also an nginx server running on the host which is bound to 10.0.0.11:443.

Thus, the port that the admin instance wants to use is not occupied, but it still complains about this as an error and does not start. I always have to stop nginx first to then be able to start iobroker.

This is what it looks like when I start iobroker first, then nginx.

netstat -tuln | grep ':443' 
tcp        0      0 10.0.0.11:443        0.0.0.0:*               LISTEN     (nginx)
tcp        0      0 10.0.0.10:443       0.0.0.0:*               LISTEN	(iobroker)

2022-08-27 11:25:24.974  - error: host.iobroker instance system.adapter.admin.0 terminated by request of the instance itself and will not be restarted, before user restarts it.

I don’t see any logical reason for this, so I think it’s a bug when checking port usage.
