Unable to Access PLEX remotely after latest update


I upgraded PLEX media server app yesterday to the latest version (Version and lost my remote access. I found with the previous version that I needed to set-up manual port forwarding. I went through and made sure that the correct IP address and port(s) were identified, which it appears they are, but to no avail. I am running Windows 10 on a new Dell Desktop PC and using an Ethernet connection via an Actiontec T2200H router. Regardless of what I have tried up to now, nothing seems to work. I am able to access all of my stuff on my LAN, but not remotely. Where do I start?
