Can't get server to see itself

I’m trying to get Plex server running on my Debian 10.0 media server running on an Intel desktop. I installed the software fine using the instructions here (I know that’s for Deb 9; should the instructions be the same for 10?). After that I can go to http://myserver:32400/web and log in using my Plex account, and it continually searches for a server, never finding it. The only authorized devices that show up on my Plex home page are my clients.

Here’s the output from systemctl status plexmediaserver

Not sure where to go from here. Help!

Server Version#:1.16.5.1554-1e5ff713d
Player Version#:n/a

is it remote or local?

  1. If remote: SSH tunnel to it. ( ssh -L 8888:127.0.0.1:32400 ip.addr.of.host
  2. Local in-cognito window, http://127.0.0.1:8888/web

If local, http://ip.addr.of.host:32400/web

That didn’t work. I got this message in the SSH session (from remote host):

C:\>ssh -L 8888:127.0.0.1:32400 root@mediaserver
root@mediaserver's password:

and my browser only shows:

You’re using Windows, but posting about Linux. I assumed you on a Linux host.

Use Putty to perform the same operation.

My client PC is Windows, the server is Linux but has no GUI installed. Windows now includes OpenSSH, which is what I used.

I’m also unclear as to why using a tunnel would be different from accessing the PLEX GUI directly remotely.

Windows OpenSSH does not work the same way putty does. Not yet, as you see in the errors

I do presume you enabled SSH on the remote host?

I started a new thread since I’m not sure if the problem is the same and I don’t want to hijack the thread. The post can be found at Plex Media Server not working on Debian 10 (Arm64 | armhf)
