Cannot claim server after password change

Plex Media Server Desktops & Laptops
1

Read post about security breach. Changed plex password from my server (Debian 12). Now I cannot access my server at https[:]//192.168.1.15[:]32400/web/index.html in order to claim it.

Firefox: An error occurred during a connection to 192.168.1.15:32400. PR_END_OF_FILE_ERROR

Chromium: This site can’t be reached

192.168.1.15 unexpectedly closed the connection.

ERR_CONNECTION_CLOSED

Server Version#:1.42.1.10060-4e8b05daf
Player Version#:

Tried the steps suggested here: PR_END_OF_FILE_ERROR after changing PlexPass/Server password - #6 by ChuckPa

But it did not work for me.

Hey!

Same here. I also tryd this:

… without success.

Any ideas?

Hi,

I had problem of not being able to access via the browser.

I logged onto the plex machine and followed the guide in the first post here:-
I can’t claim server after password update : r/PleX

Basically, I went and generated a claim token https://plex.tv/claim

Then appended that claim token to the following command which I ran in the CLI

curl -X POST http://127.0.0.1:32400/myplex/claim?token=XXXX

where XXXX is the claim=xxxxxxxxxx token

Hope that helps

Don’t use your custom domain, if you have them set up. Only the local IP address of the server.

Use the http protocol, not https.

That was it. I had the local address bookmarked using https as it generally works after adding a security exception for the plex.direct cert. But this doesn’t work for the claim server process. Using http worked. Thanks all!
