Emby notifications not working

I haven't changed the IP, port or API of the Emby device but notifications no longer work.

This is in the log:

2018-07-05 22:43:11 WARNING  Thread_34 :: [7cfc79d] EMBY: Warning: Unable to contact Emby at http://**********/emby/Notifications/Admin: 500 Server Error: Internal Server Error for url: http://**********/emby/Notifications/Admin

I think this has just started with the most recent update of Medusa. There haven't been any Emby updates for a couple of weeks. Restarting Emby - no difference.

Restated Medusa and it updated to:

But the problem persists.

Thanks for checking out.

@johnvick
Did you change the Admin username on Emby?

[johnvick]

No, haven't changed any Emby settings (other than changing the API but this was after the problem arose - but this didn't help).

[sharkykh]

I need to look into this more, because I don't have Emby installed to check that.

In any case, that's just the notification test. It should still work for updating the library from Medusa.
If all the other settings for Emby are correct, of course.

[johnvick]

It doesn't trigger the Emby library update as it did before when you click the Emby update button on the TV series screen. Emby is otherwise working fine as is the Emby/Kodi plugin setup over multiple devices around the house.

[sharkykh]

Please check the Emby logs. I can't reproduce this error.

This is the Emby log in response to sending the test command:
192.168.1.14 runs Medusa
192.168.1.192 runs Emby

I've tested this again after rebooting every relevant device - I can confirm that the library updates are now working as before, but the test notification still isn't. Probably not a problem with Medusa - thanks for looking into this and sorry if I have wasted your time.

[sharkykh]

The log from Emby did help me figure out what I did wrong with the test notification, so it wasn't all for nothing. Thanks :)

Fixed (on develop) with #4622.
