This is exactly what I had happen as well.

I'm going to give it some time. I also even went through these steps (https://support.plex.tv/articles/204281528-why-am-i-locked-o...) without success.

It didn't work for me after restarting with a new claim and when i checked the preferences it contained `PlexOnlineToken=""`.

After removing the attribute entirely it was able to successfully reclaim the server.

So a coworker suggested I try accessing my Plex instance by internal IP, not internal hostname. And that... worked. When using hostname, the way I always had for everything else, it'd show that I didn't have access to the server.

I had the same "", but after restarting all the web interface says is Connecting. Then the server just doesn't show up in the list. <sigh> Might just need to blow up my whole config and reimport everything.

I got it claimed again after several tries. I suspect they are getting hammered by a lot of people doing the same thing (changing passwords)
