Did you already have a chance to look into the remote access troubleshooting?
There’s quite a number of factors in play when it comes to providing remote access, meaning there’s so many potential breaking points.
The good news… it appears your ISP is giving you a “properly routable” IPv4 address. That’s important because many ISPs have in the meantime shifted to only offer IPv6 addresses or private IPv4 addresses that are only routable inside their backbone (but not accessible from outside their network).
It also looks like you’ve already established a manual port forward in your router. This is good because those tend to be more reliable (1 less “moving part” in this equation).
Can you actually see/access your router’s public IPv4 address on the specified public port (50000?) while outside your home network? You should be able to test this using a service like canyouseeme.org
- If this is working, this implies the issue is probably between your router and the Plex Media Server (including both endpoints)
- If this isn’t working, this implies the issue is probably between “the internet” / your ISP and the router
