No, there is no way to ‘force’ it to work. Either it is working or not.
Have you recently enabled IPv6 support on your router or your plex server computer?
Did you install a different or new version of an anti virus software?
Did you add or update VPN software?
Did your ISP give you a new contract/tariff/modem/router?
Any other modifications on the router or network infrastructure?
Thanks again for the reply.
OK, to answer the questions one at a time:
No to IPv6. While officially supported by Comcast/Xfinity these days, by default it’s always been disabled at the router level (but not at the network adapter level–just disabled IPv6 there today via the checkbox under Properties). My OS is Windows 10 Pro x64 (just got the April 2018 update package, but this problem preceded it), my modem is an Arris 6141 and my router an RT-N66U from ASUS BTW.
Antivirus: nothing but Windows Defender that comes standard with Windows 10. No change there.
No VPN ever.
No change in ISP package nor network hardware on my end, apart from a couple of router firmware updates for the N66U.
No other network modifications.
I wonder if maybe Plex got a lot more finicky about video naming or something as of a certain version? I’m not even asking for proper movie posters. Screenshots would do the trick as far as I’m concerned, but it won’t even do that. You’d think the program could just grab a couple of them from the videos themselves. No matter whether I classify them as movies, other videos*, etc. do I get any images. *in the latter case, would I use a Personal Media agent?
My next strategy is to grab all the problem videos and move them to their own folder, create a separate library for them, do the “Plex dance”, clear caches and see if any of that helps, I guess.
EDIT: BTW, are the thumbnail images that appear when you hover the mouse cursor over the “progress bar” (for want of a better term) in some subfolder of the Media subfolder?
