To what output/findings?
Do you have a manual port forward… is it visible from outside your home network… does your router have a publicly routable IP address or are you in a CGNAT situation…?

Sorry I forgot to write what my problem was. So my problem is that remote access keeps disconnecting, and I don’t know why, I have tried to follow the troubleshooting guides here on Plex, and I have watched some YouTube videos about, but I can’t seem to get it to work. My server worked fine the first month and a half, but now not so much

The remote access status “turning red” just means it didn’t work. Plex simply shows it as “green” while it’s testing the connection.

I’ve asked about the output of those troubleshooting steps to help pin down where it goes wrong.

That’s the part I don’t know, network is not my strong suit, that’s why I’m asking for help

Have you looked at the troubleshooting guide I’ve linked above?
With what steps do you struggle?

As said I have looked at the all, so yes I looked at the guides, but I still can’t the problem

There’s no one-size-fits-all solution.

Let’s start with the basics…
Have you configured your router to

  1. assign a static IP address to the machine hosting your Plex Media Server (ip reservation)?
  2. use a manual port forward, passing outside requests to your router on a specific port of your choosing to the machine hosting your Plex Media Server?

The guide has a link to a website with instructions how this can be done in different router models.

Yes, I have done that, but it hasn’t helped me.

You’re getting an error I’ve seen other gets that has been blocking remote access from establishing.

CERT: incomplete TLS handshake from [::ffff:2.110.131.215]:39588: tlsv1 alert unknown ca (SSL routines)

Stop plex, go to the Cache directory in the Plex Media Server folder, remove (don’t delete) the *.p12 file, and start plex back up. It should download a new cert.

How do I stop Plex?

How do you have plex installed on your Ubuntu system? Baremetal, SNAP, a docker container? How you quit/stop an app varies by how you have it installed…

Edit:
NM…based on your log, looks like SNAP.

  • From terminal sudo snap stop plexmediaserver.
  • Then go to the plex media server folder, wherever SNAP places it, you’ll have to look that up. And remove the file.
  • Then sudo snap start plexmediaserver

Thank you, I will try this.

It wont let me delete it, what do I do now?

Edit

It just says this

certificate.p12
Could not display “certificate.p12”
Reason: Could not parse invalid or corrupted data.

Are you trying to open it? That error looks like you are…Do you know basics of Linux? I’m no expert, but should probably read up on some basic commands if you’re using it to run a server, just a suggestion…

Use terminal to rename the file. Navigate to the directory and then sudo mv certificate.p12 certificate.p12.old

I tried to rigth clik it but delete but it wont let me

I have done what you suggest, but nothing change. I navigated to the directory, type in the command, and dont know if anything change

Show a screenshot of the terminal window when you ran the cmd. Running that last cmd would rename the file to .old, so you would clearly see that change in the folder that holds the file.

I have downloade the logs again
