The Indirect means, the connection is routed through a Plex Relay, because the client couldn’t directly connect to your server. This usually means, there’s some problem with your remote access setup – could be a bad configuration, though that’s unlikely as you stated it used to work fine before.
I would suggest you go through the basic remote access troubleshooting steps…
Create a manual port forward in your router and test if that’s accessible from outside your home network (e.g. using a service like canyouseeme.org). If it fails, it’s worth to verify if the public IP listed on their page matches the public IP identified in the Plex Remote Access settings and the WAN IP of your router.
I don’t think asking questions (even basic ones) is a lack of trust.
I absolutely believe you that it used to work.
But problem descriptions easily focus on a very specific angle of a situation, while missing other aspects. And in particular with remote access… there’s tons of things which can change that are totally outside your control (e.g. if your ISP puts you in a CGNAT setup – basically operating their backbone like a home network instead of assigning you a publicly routable IPv4 address since those are getting rare).
