    FIrst thing I'd look at would be iptables getting in the way on your PMM server...I have a centos server that when I use port mapping (vs host networking) to the docker container I have to add an explicit iptables rule to allow traffic from the outside world to the docker0 adapter.  And mine also shows the port as open in listen.  
    Here's what I run  'iptables -I INPUT 10 -i docker0 -j ACCEPT" which the 10 just puts the rule before the last reject rule (10th line).
