App.plex.tv is unable to connect to "mint-plex" securely

Plex Media Server Remote Access
1

Server Version#: Version 1.23.5.4841
Player Version#:
Plex Web#: Version 4.59.2

I can access my server:
Locally on my devices
Remotely via ExternalIPL:32400
Unable to access via: https://app.plex.tv/desktop/#!/

I’m receiving “No content available
Check your network connection and verify that any media servers are online.” or
" app.plex.tv is unable to connect to “mint-plex” securely

Its “Secure connections” setting may be set to disabled, or you may need to adjust some settings on your network. You can learn more about secure connections here" when I try to selecting my server.

Google DNS servers
Rebooted all my equipment

Please advise,

Same here on 1.23.5.4862. Directly going to internal or external IP works fine. just not to https://app.plex.tv/desktop/#!/
