That’s definitely wrong. Manual Custom server access URLs shouldn’t include the trailing /web. But I don’t think a manual entry is still required!
I was looking at this the other day, and IPv6 seems to be working automatically now.
Ipv6 support for myplex - #392 by Volts
I haven’t investigated which clients support IPv6. I know that Apple tvOS and iOS do. They prefer IPv4 when available.
So try taking it out, and then do this -
Get your Plex token:
Finding an authentication token / X-Plex-Token | Plex Support
Put it in this URL:
https://plex.tv/api/resources?includeHttps=1&includeIPv6=1&X-Plex-Token=TOKEN
It will show the URLs that Plex is registering with the Plex cloud.
