plex media server does not run

Hi, when I try to run plex media server to do first time setup, all I get is a blank browser window that says “waiting for http://127.0.0.1” and never loads the Plex interface. I’ve checked to make sure all the firewall rules are correct. Not sure what else to do. I just paid for Plex Pass so it would be great to get this working. Help!

Do you get to the sign in screen

No, the sign in screen doesn’t even show up. The browser window is blank white like it’s endlessly loading something but nothing ever appears.

http://127.0.0.1:32400/web

http://127.0.0.1:32400/web is what I’m trying, nothing happens, just endless blank browser.

Go dig into the file system itself (/var/lib/plexmediaserver/Library/Application Support/Logs on Linux) and grab the log files. Please attach them here with your next post. It will tell us what’s happening

Logs are attached. Appreciate the help.

And here’s a screenshot of the browser. Just a blank screen.

Are you using IE 11?

If so, switch to Firefox or Chrome. There is a known problem with it.

Tried Chrome, it’s the exact same problem.

Now you just went beyond my windows skills. I’m the Linux guy. I’ll get a Windows ninja in here to help…

Thanks. If it can’t get resolved how to I contact Plex for a refund? Can’t
find anything on the website.

You’ll have to ask the folks via the Contact Us (found on the Plex.tv home page) if you want a refund.

I do find it very hard to believe it won’t run on your computer though… I’ve never seen this happen.

Do you have an antivirus/something which blocks JavaScript and/or popups? (that’s what runs for the start page to bring up the setup wizard). If you do, please disable it temporarily

I do not have any antivirus running, I even disabled Defender and that
didn’t work either.
I’m not aware of anything that would block Javascript since other JS-based
sites work fine.

You’ve done an uninstall / reinstall?

The only thing I can see is where the Agents “aren’t known to the system”. That sounds like a bad installation to me. I think those are recorded in the windows registry.

Yeah I’ve uninstalled/reinstalled three times. Same result.

I think my machine is not able to access localhost for some reason. I’m
getting the same issue with Emby and it uses similar localhost access. But
I don’t know how to fix it.

ok… that tells me you have a machine problem but there might be a work around. If not, you’re going to have to get windows itself fixed or reinstalled. (yuck)

get the IP address of your computer (network settings) and TRY.

http://ip.address.of.computer:32400/web

If it’s IPV6 (that ::FF80:; stuff. that’s part of the problem.

make sure IPV4 is enabled in your Network Adapter - Properties. You should see TCP-IP and be able to tell it’s the 4-digit one, not IPV6.

The additional logs in C:\Users\hystou\AppData\Local\Plex Media Server\Logs\PMS Plugin Logs folder together with the corresponding server logs may give some more clues

Areas to look into:

Firewall - ensuring there is an inbound port rule:
Protocol: tcp
local port: 32400
remote port: any
remote IP: any
Programs: any
Action: Allow
Scope: all profiles

Firewall - ensuring C:\Program Files (x86)\Plex\Plex Media Server\PlexScriptHost.exe is listed as allowed program
and the other exe’s in that folder

Does Plex require Python to be installed? If so that could be the issue I
suppose, but the installer said nothing about Python.

No it does not. It uses its own version of python code which is part of Plex Media Server program set
