Suddenly Remote access isn't working - Outside network appears and then fails

On a whim, I tried something that I found in another, similar, thread and so far, it seems to have fixed my issue. I’ve seen remote access green for 5 minutes now, which is a near miracle.

I followed the steps here Synology FAQ - Questions, Answers, and a few How-To's

Although these are for the Synology platform, I extrapolated the details to use ssh/vi to chage it on my qnap. Short list is I:

  1. Shut down the plex service on my qnap
  2. deleted my server from the app.plex.tv site
  3. Signed out of app.plex.tv
  4. Modified the preferences.xml file
  5. started plex back up
  6. used a private browsing tab to navigate to the internal IP of my plex server
  7. at this point it deviated from the linked doc. I just hit a “finish” type button where it referenced my media config being good to go (Sorry, I can’t remember the specific page it showed me). It then took me to the main plex page, lots of yellow !'s everywhere. I just went to settings>general and signed in.
  8. dis/re-enabled remote access
  9. profit
