Plex server suddenly won't connect, even on host machine

EDIT: SOLUTION HERE All media server v.1.18.x updates cause server unreachable/unavailable after update

Original post:

I migrated my plex server to a new windows 10 machine and everything worked great for a couple of days. Now I cannot access the server even on the host machine. It isn’t accessible to any other machines on my network. I haven’t updated anything that I’d think would affect it.

I look at the logs and I see endless:

and

It looks like it’s getting hung up on authentication? What’s it trying to do?

Server Version#: 1.18.3.2156
Player Version#: various players, none work, even on host machine and web interface using 127.0.0.1

edit- Oddly enough, I can connect through my Sony/Android TV, but it still won’t connect on the host machine using the web interface.

So after repairing the Plex MS install and rebooting everything about a hundred times, I can access the server by any means except for the web interface (both local and remote). This includes an android TV, amazon kindle, android phone, sony playstation, etc. Any tips on how to troubleshoot plex when the web interface is the only thing giving you trouble?

For whatever reason, when I open a web interface in my browser, PMS starts using 30-50% of the machine’s CPU. When I close the browser window, it stops using the CPU to that extent.

Hi @Ushmel - your situation sounds similar/related to one that I and others are experiencing, posted here

Start the browser in private/incognito mode and see if the symptoms reappear. If not clear cookies/browser data and try regular.

That sounds almost exactly like my problem. Thanks for posting. I was worried it was my database or something. I’ll just wait and see if there’s a fix for it in a later version.

Using incognito/different browser produced the same problem, no changes on that front.
