Remote Access Disabled for Real Clients Because Plex Couldn't See My Server

This one is bugging me too Ive wasted nearly 2 days trying to sort this and getting pretty p off with it, nothing on my system has changed no updates it just stopped working from outside my network, also inside, its like when remote is enabled my local clients cant connect as they then try outside the network as if the server is not available, then if I try and access a file it will run then when I check the settings again remote access is still enabled but not available outside my network and then no clients can connect until I reset the connection again (all firewalls off during testing!)

My post is here for my logs it seems as if the remote access service is toggling on and off between the internal and external, I just dont get it I used it over Xmas with no issues!

Is a re-install worth considering!
