[mythtv-users] BE4 – Remote Frontends not connecting

[Barry Martin]

Hi Folks!


Me again – different problem with a different backend. Actually I was 
working on this new BE to replace the old one that had the crash and 
database corruption issue.


New system running Ubuntu 20.04 and MythTV version 31.


Two issues:

     Remote Frontends not connecting.

mythfilldatabase/SchedulesDirect not updating (I have seven days’ of data).


Frontend issues:

     Local FE (on the Backend) works

     From a remote computer: Firefox to 192.168.4.4:6544 works (IP of 
the Backend)

     Remote Frontends not connecting


Frontend will see on “MythTV Servers” screen

     MythTV AV Media Server (with a ‘91’ under)

     To the right side 31.20200101-1 and an unlocked lock icon

     Pop-up window: “Cannot login to database”


Frontend Database Configuration Screen appears correct:

     Hostname 192.168.4.4 (correct)

     Ping checked

     Port 3306

     Database Name mythconverg

     User mythtv (tried ‘barry’ too!)

     Password (correct)

     Enter Custom Identifier for Frontend Preferences unchecked

     Enter Database Server Wakeup unchecked


Examining Log to Terminal: typed ‘mythfrontend’ on BE4:

     In red (orange-red?) Cannot load libcuda.so.1


Per https://forum.mythtv.org/viewtopic.php?t=3640 
<https://forum.mythtv.org/viewtopic.php?t=3640> “[Solved] Remote 
frontend won't connect to DB”

> The backend settings in mythtv-setup define where the backend listens. 
> A 127..... address would be for a combined FE/BE with no remotes.

==> mythtv-setup → General → Host Address Backend Setup ==>

Security PIN 0000

All Connections on all Subnets unchecked

Listen on All IP Addresses checked

Primary IP Address/DNS Name 192.168.4.4

This Server is the Master Backend checked


Last post of the same topic (t=3640, above) says “I had to edit 
mythtv.cnf to correct the bind-address from 127.0.0.1 to my ipaddress. 
My version was located in /etc/mysql/conf.d”.


Mine just says:

     [mysqld]

#bind-address=:: <== so commented out by default

max_connections=100


FWIW I was creating this Backend on 10.0.x.x network if that makes any 
difference/helps find my error.


Thanks again for all the help!
