[mythtv-users] repeated mythbackend online messages on remote frontends

[Mark Perkins]

Sorry - lets try that again.

I am getting repeated "mythbackend online" messages popup on my remote
frontends (I don't have a local frontend to test due to being a headless
machine). No fixed interval, about 1 every 30 - 120 seconds. This is the
sort of thing I see in the general mythbackend logs:

Basically sockets getting opened and then closed due to disconnect nearly
immediately.

Everything else seems to work fine. Playback, recording, mythweb. I can't
fault the performance everything is still working smoothly. I am just
getting a lot of the little popups which is a tad annoying.

Unfortunately I have had a massive rework of basically everything recently.
New house, new network, new pFSense gateway, new internet connection, OS
upgrades from Centos 7.3 to 7.4 (about 1200 updates, it had been a while
since I last pulled updates). Pretty much everything has been touched except
the backend and frontend hardware.

My question is - where should I be looking first for the probable cause? My
thoughts are either something to do with routing (ie the pFSense gateway) or
else my backend (fixes/29) is running in a docker container so maybe some
docker change.

Does anyone have any suggestions on where to start?
