Thanks for the link, so answer is "No" ... in fact Unraid connect seems to have a reliance on other servers that would increase the potential for downtime?
"If the Internet goes down and you lose access to DNS, do the following:
If Use SSL/TLS is set to Yes, then you can access your server using: https://[servername].[localTLD] or https://[servername].[localTLD]:<https_port> (if your https port is not the default of 443)
If that doesn't work, or if Use SSL/TLS is set to Strict, then using telnet, SSH or local keyboard/monitor log in to the server and type: use_ssl no
Now you will be able to access your server's webgui via: http://<ip_address> (note: http not https) or http://<server_ip>:<http_port> (if your http port is not the default of 80)
When the Internet comes back, navigate to Settings -> Management Access and set Use SSL/TLS back to Strict to re-enable local SSL."
Doesn't appear to be anything that would make Plex server installation easier?
