Trouble with Plex on Synology + New Unifi network

Hey all, I am coming here because # I’m a fan of SpaceRex’s work and I’m hoping that someone here has found a solution to what I’m experiencing.

I have Plex running on my DS224+ and it works great. I recently decided to upgrade my Synology 2600 to a Unifi Cloud Gateway Ultra and a U6-LR Access point. Ever since making the move Plex has been having trouble connecting to my Plex server running on the DS224+. For a day or so I was able to access but only with an “indirect” connection. I did some digging and found some others with this issue but without a clear resolution. https://www.reddit.com/r/PleX/comments/q0jl30/plex_synology_and_unifi_help_needed_with_port/

I’m curious if anyone else has been able to successfully use Plex on a Synology within a Unifi network. I have to imagine this possible but I am lost as to what to try next.

Thanks ahead of time.
