[mythtv-users] Frontend cannot connect to backend after upgrade from 0.28 to 29

Thanks Leo, your email lead me to the fix, although I'm not really sure why
it worked...

I stopped the backend - which had similar MythSocket errors as seen by the
user who created the issue in the link you posted.

I then ran mythtv-setup and went to the General page, didn't change
anything (all settings were correct already) but saved anyway. Then exited
mythtv-setup.

When exiting, mythtv-setup complained about not having write-access to my
mythtv/livetv folder, which I fixed (surely this wasn't the cause).

I then started the backend, then the frontend, and all was well.

For reference, I have never set up an ip6 address on my home network,
including mythtv.


Cheers,
Justin.
