Lost connection to LMS, think port 9000 is blocked

Hi all,

So last night all of a sudden I lost connection to both the LMS web UI and all players lost contact to LMS. Interestingly I can connect to mysqueezebox so can get deezer etc., but nothing local. Restarted LMS service, restarted router and server, but nothing changed.

I can ping my server no problem and access the music folders via a Samba server. However, when I opened a telnet link to the 9000 port from my laptop I get

Connecting To 192.168.0.8...Could not open connection to the host, on port 9000: Connect failed

I've checked the LMS log and it seems to start fine, but then all connections time out (see below)

Checked using netstat and 9000 is active and listening, but seems to be sending nothing out (see below).

I'm pretty confused. It seems like the port is blocked to out-going traffic.

I'm running LMS 7.9.1 on Ubuntu 17.10 server. SBs are Touch, Receiver and 2 radios, all using wifi.

I'm no Linux wiz so if you could include commands to use if asking me to do stuff, that'd be great.

Any help would be appreciated. Thanks in advance,
