If you are trying to setup two cms instances on the same server, it should be possible, however from the log above, which I don’t fully understand, it looks like the db container is listening on all ips. Which is fine, however the reverse proxy will need to be specific on how everything is being routed. Also the two setups will need to also use different ports and different file paths.
I have not tried to setup two Xibo instances on one server so I can’t really tell you more than that. You may want to shutdown one instance at a time and see if by themselves they work. If so, I think you have either a port or file paths conflict.
