Windows VM Port not accessible

Question

I recently installed windows 11 vm on azure. I have python installed and running a fastapi uvicorn app with port 8080 listening on 0.0.0.0. I have created inbound rules for 8080 but the port is not working from public ip. But inbound rules for rdp port and ICMP is still working for the same VM. What is the real issue here? Can anybody give a hint what is the problem? I have disabled windows firewall also.

Hi BRAHMACHARIMAYUM,

I recommend you to troubleshoot your issue with the FastAPI app on port 8080, ensure that the Network Security Group (NSG) rules allow inbound traffic on port 8080 and verify that your application is correctly bound to correctly on local 0.0.0.0:8080. Also, confirm that the public IP is correctly associated with your VM, and try accessing the app from different devices or browsers. Restarting the VM or services might also help apply changes correctly
