Hello,
Since I moved from a 1Gbps connection to 500Mbps, the accounts I share access to my library with and who want to watch a movie in 4K have a greatly degraded image quality, down to 720p or even worse, resembling a terrible DivX quality.
If you have any ideas, is it because the connection is too weak? Or are there specific settings to adjust? Perhaps my configuration is not optimized anymore?
Thank you in advance if you can help me.
If your upload speed is 500mbps you shouldn’t be having a problem with every person trying to stream
It sounds to me like something with your remote access got messed up during the downgrade
Look in the dashboard as someone tries to play a remote stream and see what it says here

If it’s configured properly, it should say remote. If it says indirect like my screen shot something is wrong and you need to troubleshoot
Hello ! Thanks for your answer.
so i have this
Yeah, that is what I expected. As you can see you have “Indirecte”
This is what is referred to as a relay connection. With a Plex pass you are limited to a maximum of 2mbps.
You have something blocking the port you used when you port forwarded Plex in your router. You have to follow the guide I linked to find out what that is
Is this the same internet company?
I am limited with plex pass ? how to be unlimited ?
nope not the same
i have to forward the port on the router ?
You are limited to a 2mbps connection using a relay. It’s only 1mbps without a Plex pass. If you configure your remote access properly you are not limited at all

You have to configure remote access using the links I provided.
You may also have to contact your ISP to make sure they even allow this
Im trying everything im losing it…
I did the forwarding 32400 TCP, i have a fix IP address…
When i apply on plex settings; its green and then turn back red…
Your ISP, which, at those speeds is most likely a fiber provider may be the block. I have such a provider (Greenlight, upstate NY area) and they use something called Carrier NAT, which will give you a public, routable IP address, but nevertheless blocks incoming traffic that is unrelated to an existing connection. I have to have their static IP service to get around that. (I don’t use it for plex, but I need it for other things).
Try to get on a network outside your home network and try to connect to something from there; SSH, or whatever you have available. If you can’t connect, note the time that you try, and then look at your firewall logs to see if there was a connection at that time. If there is no “knock on the door”, it’s likely your ISP is blocking.
That is the problem here. You are probably behind what is called a CGNAT, which stands for Carrier-Grade Network Address Translation. This is a PITA problem for people like you that want to host your own server accessible to the internet.
Normally, ISPs have thousands of IP addresses that they give out to their customers (you). Some, however, have only a few (or one) IP address given to them. So what they can do, is create their OWN internal network of private IP addresses, and give those out to their customers (again, you). If this sounds familiar, it’s because it’s what your router already does inside your house. Your house gets one IP, and all devices within it get a private IP address. Routers will then use NAT (technically, I think it’s more like PAT?) to allow internal IP devices (your computer) to talk to the internet with a public IP (the one used by the router).
With NAT, outbound traffic can flow safely to the internet and back, but any traffic that doesn’t START inside your house is usually blocked by default. To allow traffic that starts outside the house to reach inside, you must open up these “ports”, and forward any traffic to that specific port to your server.
With CGNAT, you are now behind two (or more) routers. So you now have to forward port traffic from every router along the way to the next. In a CGNAT situation, your ISP will NOT allow you to port forward on their router, so what you must do is request a public IP address from your ISP. This removes their router from the problem, allowing you to make do with a single port forward in your router.
This article has some good information. The link should take you straight to the section on “Common problems”, which starts out explaining how to detect and possibly fix double-NAT situations (such as CGNAT)
There is no guarantee that you can fix this. Some ISPs are simply unworkable, and the only remedy is to change internet providers.
Hello
Just to say thank you for the replies. I fixed the problem.
So here was the solution for any Luxembourgish mates with Post.lu + Fr!tzbox :
Thank again, have fun
