What do you mean by "blocked"?
i was doing a steps how to make a server but it the end he said chack if its open or not
Are you trying to setup a server on your PC?
yes
Most IP addresses assigned by providers are "gray," meaning they are behind NAT.
So you won't be able to open any port
oh
so its my router problem right?
am using archer ax20
Yes, if you do have a dedicated IP address, you can open ports on the router.
so i can fix it by doing some settings right?
Not in all cases
With "gray" ip address it's impossible to open ports.
i talked to tp-link about opening them will they can or i need to buy new one "router"
thx for the help @TurboVadim

We may have bad news for you :C
You may be under a CGNAT which is a method that ISP's use to conserve IPV4 IP's due to how limited they are now. What this means in plain terms is that your IP address is being shared with other people as your router goes to the ISP's router, by default this means port forwarding doesn't work.
We need to check if you are under a CGNAT and we got 2 options.
Option 1: commands
Depending on your OS, run the following command:
- Windows:
iex (Invoke-RestMethod -Uri "https://raw.githubusercontent.com/DominicTWHV/Is-It-CGNAT/refs/heads/main/windows.ps1")
- Linux: curl -s https://raw.githubusercontent.com/DominicTWHV/Is-It-CGNAT/refs/heads/main/linux.sh | bash
-# You should never run such things without reviewing and understanding the code
Option 2: manually
Open your router's configuration interface. Somewhere, you'll see something like 'external' or 'public' IP.
If your external IP is in one of the following ranges, you're basically screwed as long as port forwards go:
- 10.0.0.0/8
- 172.16.0.0/20
- 192.168.0.0/16
- 100.64.0.0/10
- any IPv6 address/range - This shouldn't be a problem, but Minecraft's IPv6 support is still rather quirky. You're at your own, but we're happy if you share your experience.
What do I do now?
You should ask your ISP for a public and IPv4 address (but this may cost you money).
NB: your internal IP should and most probably will be in one of the first three ranges, don't mix them up
