I have an Ubuntu 20.04 server in azure to which I can connect throug ssh. Nevertheless, I am trying to open other ports (6000 to be specific), but it is impossible for me to access the server through other ports other than 22.
I am following every tutorial on the internet, all of them say the same: Go to VM Resource --> Networking --> Add Inbound port rule. It does not work.
As you can see, port 6000 is wide open for all traffic, and still it cannot be accessed from other computer.
Please, this is not the first time I encounter this issue. For work reasons, I have opened many other virtual machines and for some reason I fail to understand, I can only access opened ports in some of the virtual machines. Please, I have no clue of what is going on, and it is really anoying to deal with this. I have tried to open the ports through the iptables configuration but still I can't access any port.

Thank you for reaching to Azure Community Forum.
Please check if there are services listening inside the machine for the custom port and whether OS firewall has these ports opened. To check the service listening on port you can use following command:
netstat -a
https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/netstat
Let me know once you have checked inside the machine.

These ports are open on the operating system, but I cannot access the server through these ports. I even tried to choose no nsg when creating a VM, but I still couldn't use ports other than 22.
