I have seen others threads on that subject but no one came up with a definite solution it seems.
I have tried:
Re-start PMS on Synology
Removed DVR and re-install
Refreshes of guide
Limiting # of channels
I’m thinking of removing plex all together on my Synology and re-installing it and the DVR as well but before I do that, I thought I’d ask for help and show my logs in case somebody can see something obvious.
There was an issue giving rise to JSON Parse Error where the response for the guide refresh contained error 403 Forbidden. This should be fixed now.
Additionally Plex Media Server beta 1.14.0.5465 has retries for failed requests to fetch the guide - so that in itself would have helped whilst the issue was there
Please do manual update to the guide and once that completes ok, then incremental updates would ensure the guide remains up to date
If problems persist, please provide fresh logs from the server with debug logging enabled beforehand and also a zip of the Diagnostics directory which is within the Plex Media Server data area
