I eventually get in but I get weird sign in errors:
Standby please. I’m checking with operations now.
Which region of the world please?
@ChuckPa, thank you so much. I am in US.
There have been some issues with the North American systems today.
Of particular note are the name servers.
Would you please restart PMS and see the condition clears?
Without retarting, it’ll wait for at minimum 1 hour before attempting again.
tried restarting, I get a bit further but now I’m stuck with completing and when I get behond the page I still can’t claim the server. 
Maybe I just have to wait? Not sure here.
Ok… so a lot further.
Now to undo what PMS has most likely done because its been left unclaimed so long (It secures itself).
-
sign out of the Plex/web again and close the browser
-
Via the command line, as root -----
-
Edit /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Preferences.xml
-
Look for and remove the following
Name="value"pairs
a. PlexOnlineHome
b. PlexOnlineEmail
c. PlexOnlineUsername
d. PlexOnlineToken -
Save the file
-
Make sure it’s still owned by
plex:plex(ls -la)
7 Start PMS
Now, it will be a completely unclaimed machine (as if freshly installed) while still keeping its basic identity (this is how we fix being locked out )
thank you very much. This gets me even close but I still cannot claim the server and I get all sorts of login/sync errors. If it has something to do with preferences and configuration, Is there a way to uninstall Plex and then reinstall it?
Show me the log files please? (tar.gz or ZIP)
Do I just attach them here?
yes. attach, let it upload and show a URL… then “Reply”
There is quite a few here
plex_logs.tar.gz (486.7 KB)
That’s what I want. I’m all set up to view them.
It doesn’t like your password at Plex.tv
Go to Plex.tv -> Account - Settings
CHange it.
While there, there is a checkbox -> Sign out all devices. Check it too.
You’re using IPv6. That’s a no-go
you need the IPV4 stack
Given your machine is favoring V6, you will need to expressly state:
127.0.0.1 instead of localhost
-or-
edit /etc/hosts and clean that crap out of therer 
Did this and cleaned out all authorized devices too.
Now for the IPv6. Can’t use that to claim the host.
Plex.tv is still IPv4. IPv6 is only partially implemented.
If you don’t need IPv6, turn it off . It will only cause you grief.
Not sure why it is doing that as I did not put anything special into the file.
cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
Do you mean remove that IPv6 line (line 2)?
thanks, How can I turn this off? I though that the system auto determines this, no? I can also use 127.0.0.1 I suppose.
Fedora should auto select but PMS, in prep for IPv6 also listens on V6.
Fedora checks V6 first… and off the cliff we go 
Upper right (if Gnome) → Settings - Network → specific Adapter → Settings cog → Ipv6 tab – Disable. Apply.
Got it. Thanks. I disabled IPv6 and restarted NetworkManager. Should I try again?
