Can't connect since updating server machine

Hi All,

A few days ago, I updated the OS on my server machine. It's now running Xubuntu 18.04. I think that it was 16.04 before the update.

Everything else seems to be working fine since updating. Even MythTV is still working! :-) This is the the big one that usually goes wrong for me with with updates.

However, my 2 squeeze devices can no longer connect.

On my computer, http://192.xxx.xxx.xxx:9000/ can't connect either.

Even on the server itself, http://127.0.0.1:9000/ can't connect.

However, if I run:
$ service logitechmediaserver status

Then it seems to be running ...

I think that I tried to re-install logitech media server after first seeing this problem, but that didn't fix anything.

How can I sort this out?

Thanks,
Damian
