After setup, openfire (admin-console) does not listen on port 9091

I am using netstat/ss to verify this - OF does not listen, so I cannot acess via 9091. BTW, there is only IPv4 on this server.
(The default http-port [9090] works, but I wanto to disable it).
Any hints would be great!
Running OF 4.7.5 on devun/chimaera.

OpenFire and/or it’s docs are probably limited - after I disabled port 9090 and set the calue -1 into the config-file, restart OpenFire and all is good - at least, it listens on 9091, but no longer on 9090.
Can someone confirm, that OpenFire can only listen on one port?
So the statement:

Disable either port by setting the value to -1

is never true or clear. Why did port 9090 initially work even though 9091 does not contain -1 ??

I’ve never observed this behaviour before. Which JRE are you using? How was it configured? Was it set up as a 4.7.5 server, or upgraded from something else?

I am using OpenFire 4.7.5 on devuan4 (chimaera) and on debian11 (as of today), both with java:

default-jre-headless/stable,now 2:1.11-72 amd64
default-jre/stable,now 2:1.11-72 amd64
openjdk-11-jre-headless/stable,stable-security,now 11.0.18+10-1~deb11u1 amd64
openjdk-11-jre/stable,stable-security,now 11.0.18+10-1~deb11u1 amd64

On the second (debian, as of today), after setup I initially disabled the non-secure port (9090) and restarted. Nothing is listening on 9091.
So your browser is allowed to push your initial admin password to a destination of its choosing :sweat_smile: because there is no (easy) escape.
The behavior so is similar to that I initially described.
Never use a webbrowser to mange services in the internet.
