Random issues with remote connections not able to see server or only see it indirectly

Server Version#: 1.30.1.6497 (says its up to date)
Player Version#: various different players

i keep having issues that randomly go in and out. even will act differently for separate users accessing server at the same time. sometimes users can’t connect remotely at all, even though the remote access says its fully available outside my network. sometimes they can connect but only indirectly, even though the day before they connected securely with the same device.
i’ve also noticed that under the ‘fully available’ message on the remote access setting that many times when users are having these problems the section that would list my IP address is unable to display an IP.

what would cause the IP to not get loaded here? i recall one always being there before these problems started.
i’ve tried manually setting a port, setting up port forwarding in my router, stopping and starting plex server, rebooting server… sometimes the IP would come back on one of these steps but this time nothing is working.

Most common causes
– DNS / Gateway addresses incorrect
– Using multiple ethernet adapters on the same subnet without configuring properly / bonding together
– Non-RFC 1918 compliant home LAN.

What is your LAN configuration ?

DNS set to google’s 8.8.8.8, gateway set to router’s IP
i have no idea on RFC 1918
i did have 2 ethernet cables plugged in and no bonding. so i’ve unplugged one of them. just to start fresh i disabled remote access, stopped the plex server app, restarted plex server app, logged into plex and clicked enable remote access again. now for 10 mins its been sitting there spinning trying to connect to server:

guess i just needed to refresh the page. it showed again remote access enabled but no IP showing (like pic in original post) and remote users still connecting indirectly

When you change the networking in DSM , you really should restart PMS at minimum.
If you have docker containers , it’s best to restart the whole NAS.

Having checked Plex.tv, your server isn’t showing as “Published” (Remote Access enabled)

The easiest next step here:

  1. Remote Access enabled
  2. One ethernet cable unplugged
  3. Start DSM
  4. Let it all come back up clean

enabled remote access
1 ethernet cable connected
restarted dsm
still seeing same reaction with remote connection : o(

Hey @kiddtaylor!

I too have a Synology and I think I had a similar issue. When I first setup my PMS, I had to open the Port that Plex wanted on my Router via Port Forwarding. DSM did not seem to care one way or the other. I also had to set it as TCP and not UDP as UDP also had issues. It’s been solid from then on.

Hope this helps :slight_smile:

i had turned on port forwarding at one point and it wasn’t helping. chuckpa got me on the right path and things looking good for now. had ipv6 settings still in place from when i was in europe, and i guess it just took this long to really mess with me.

If I may summarize here for all ?

What we found was IPV6 enabled

As the internet changes to IPV6 , vendors are setting up their software to favor IPV6 over IPV4.

Plex.tv does not yet support IPv6 directly.

What happened here is:

  1. The IPv6 address was retrieved from the ISP
  2. The IPv4 address was ignored
  3. The IPv6 address got sent to Plex.tv.
  4. Plex.tv didn’t know what to do with it.
  5. Remote Access failed to report a valid IP
  6. Everything stopped.
