Web UI can't find Plex server

Plex Media Server Desktops & Laptops

I haven’t used Plex on my Linux machine in a few months, but when I logged in today and tried to use it, I found that Plex was no longer working. When I open the “Plex Media Server” link from the “start menu” in Linux Mint, it launches a browser tab with this URL:

http://localhost:32400/web/index.html#

I can log into my Plex account on that page, but I see this message too:

“A server could not be found. Download and install Plex Media Server, and it will appear here.”

I definitely already did that before, which is how the entry was added to my “start menu” to begin with. If I open a terminal and check, I can see that Plex is indeed running:

Why isn’t the web UI connecting to the server?

A Plex server in your account last has been seen by plex.tv 2 weeks ago.
Are you sure you are still using this plex.tv account for your server?
Are you sure that your server is still running?

Yes, I’m using the correct account (the same account I always use). It was probably seen two weeks ago because I turned on my computer and the server started up and “phoned home”. Yes, I’m sure the server is running; see the ps output that I posted above.

What happens if you go to app.plex.tv instead?

Oh interesting, that works immediately! I wonder why the local link isn’t working.

Then keep on using it. At least until the web app version number has been updated with another server update.
