Unable to log into Plex Web View

So, I was tinkering with the Plex Media Server settings and then suddenly I got this error in Chrome from my desktop.

“Plex didn’t send any data”


Visiting my server from worked – really weird.

So, going back over what changes I had made, I found the culprit.

Under the Plex Settings > Settings > Network menu option, I had modified the IP6 “Secure Connections” from “Preferred” to “Required”.  I changed this back to Preferred and that immediately fixed my issue and the web view was working again.
