Server Version#: 1.25.6.5545 Player Version#: 4.69.1 So I have a server which is in a Datacenter - so there’s no NAT, NAT64 etc, it’s got both IPv4 and IPv6 as public IP’s. No matter what combination I try of custom server URL in Settings → Network, I cannot get the streams to work via IPv6, they…

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 w…

Done - no change unfortunately. The api call shows only IPv4 addressing, in public address and connection protocol data. Have verified that 32400 is open to IPv6, so kinda at a loss here.

Dumb question, but I assume Settings → Network → Enable server support for IPv6 is checked? And the server has a GUA?

Eep! Sorry, I copied the URL wrong before. Try this! https://plex.tv/api/resources?includeHttps=1&includeIPv6=1&X-Plex-Token=TOKENHERE

Yes - it’s in a datacenter, so it has an 100% static IP. Fully routable, available, I can get to it from my connection and DNS AAAA record has been added. Have done a port scan from an IPv6 host and port is open. Enable Server Support for IPv6 is ticked.

Datacenter doesn’t imply IPv6! What’s the prefix? Somewhere in 2000 to 3fff? Wait - now I’m lost. What’s been added? Are you trying to use the automagical blah-blah—blah.guid.plex.direct names and certificates, or your own hostnames and certificates? If you want to use a personalized URL, the …

Yes I understand, but as I’m the network engineer I know it’s ipv6 :wink: It’s dual stacked with a v4 and v6 static - as it’s in a DC there’s no DHCPv6/SLAAC or RDNS, it’s all 100% manual (but definitely v6) Purely for my own use and testing - it’s just so I can use a hostname, but it doesn’t ch…

[image] doogienz: I’m the network engineer I know it’s ipv6 :wink: That’s even worse! lol We know that Plex is particular about IPv4 address ranges, and I noticed that it doesn’t register IPv6 link-local addresses. That’s why I’m curious if you’re using addresses from the official GUA range. …

I’m curious. What happens if you set Settings → Network → Custom server access URLs like this? http://[colon:separated:ip:v6:ip:addr:like:this]:32400 Note: Include the square brackets. Is it then published, using @Volts directions above to test? On my own server I can publish valid IPv6 address…

[image] pshanew: unable to detect your IPv6 address AFAIK the Plex Media Server identifies its own IPv6 GUA and ULA addresses and publishes them. Or if you manually enter an address (in the format you describe) that’s immediately published. I don’t see any “detection” of IPv6 from the Plex …
