Plex is not reachable.?

[Cheridon]

I installed PMS on CentOS 7.6, I used putty to access the server and after setting the server up and claiming it it started saying " Plex is not reachable.

Make sure your server has an internet connection and any firewalls or other programs are set to allow access."

I’ve tried everything I could think of but can’t seem to figure the issue.

When I run “curl https://plex.tv/pms/:/ip” it shows my server WAN IP Address .

The steps I took are:;

1. Installed CentOS 7 and installed all system updates and installed wget and nano
2. Disabled SELinux, Changed SSH Port, Disabled Root and Enabled SSH Keys
3. I installed Plex
4. SSH Tunnel with PuTTY with my source port as “32400” and my destination as “localhost:32400”. Accessed “http://localhost:32400/web” from Google Chrome and Firefox
5. Everything loads fine, I go through the usual setup process; no issues.
6. I enabled remote access to the server so I can access it without the SSH tunnel, I claimed
   the server and after logging in my server disappears and I can see my other servers and when I try accessing it via putty using localhost is says "Plex is not reachable.

Make sure your server has an internet connection and any firewalls or other programs are set to allow access." but I can access my other Plex server using theserver WAN IP (server wan thats saying plex is not working)

What I don’t see listed is either punching a hole in the firewall, or disabling the firewall completely…

I’ve already tried disabling the firewall and rebooting the server a few times.

What does “wget -O - http://plex.tv/:/ip” come back with?

Your methodology looks an awful lot like what I did (CentOS 7.6.1810) here. Installed cleanly, initial localhost configuration went fine, remote access configuration went as expected (manual, not uPNP.)

Just for grins, does forward and reverse DNS lookups work on another client on your network, referring to your Plex host?
