[mythtv-users] Frontends can't connect

[Phill Edwards]

I've just done a new installation of MythTV 34 on Xubuntu 22.04. It was all
working with remote frontends connecting and the Web App connecting on
http://192.168.0.120:6544/.

Then I don't know what happened but it stopped working and I can't connect
any more.

If I go to http://192.168.0.120:6544/ it says:

    This site can’t be reached
    192.168.0.120 refused to connect.

And the local frontend on the same machine as the backend can't connect. It
says
    Unable to connect to master backend.

And the remote frontend gives the same error.

Mythbackend.log has these lines which I suspect means something is wrong:

Mar 24 14:07:48 MBE5 mythbackend: mythbackend[3311]: I CoreContext
mythcontext.cpp:891 (TestDBconnection) Start up testing connections. DB
localhost, BE , attempt 0, status dbAwake, Delay: 2000

MySQL is running and I can connect to it from the command line.I have these
lines in mysqld.cnf. I changed 127.0.0.1 to 192.168.0.120 in order to allow
the remote frontend to connect and that was working nicely earlier.

###bind-address         = 127.0.0.1
###mysqlx-bind-address  = 127.0.0.1
bind-address            = 192.168.0.120
mysqlx-bind-address     = 192.168.0.120

Any ideas why nothing can connect?
