Three unsolicited thoughts / considerations:
-
You don’t need a Plex Pass membership to use a Plex Media Server (only for certain advanced features and Remote Access isn’t one of them).

You shouldn’t need to setup remote access to be able to stream media from your servers in clients / Plex apps running on the same network / subnet
-
Remote access has a number of dependencies (not all of which are under your control) – sorry to say, but hitting various (random?) settings on a router is like playing lottery, you can get lucky but it’s highly unlikely.
- Did you already have a look at the related troubleshooting support article?https://support.plex.tv/articles/200931138-troubleshooting-remote-access/
- There’s also a guide with some more details on how to troubleshoot remote access issues (e.g. starting with pinning down if this is an issue with your ISP, your router / router settings or the machine hosting PMS / PMS itself / some bad configuration).
