time out for access flask app on azure VM - azure

Question

I have a flask app running in a docker container on an Azure vm.
App is running at port 5000 and I'm exposing that port to docker
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
57cdce7b5b2b auto_ml2:latest "/bin/sh -c 'python3…" 6 seconds ago Up 5 seconds 0.0.0.0:5000->5000/tcp serene_mcnulty
mlcontainers2#automl:/$
I'm trying to make the following API call:
headers = {'content-type': 'application/json'}
url = "http://XX.XX.X.XX:5000/api/AutoML"
resp = requests.post(url,data=json.dumps(data), headers=headers )
But after a while, I just get a time out error:
Failed to establish a new connection: [Errno 110] Connection timed out'))
I thought the port must be closed, so I added a rule for it and opened ports 80 and 5000-6000 and reboot the VM
But I get the same error after this.
EDIT
I tested it from the VM, there it works fine:
But from a remote request I keep getting the same error:

For this issue, first, you need to make sure that you can access the container from the image inside the VM. Then you need to add the rule to allow all the TCP ports necessary in the NSG which associated with the VM. Finally, you can access the API server outside the VM via the VM public IP with the right port which allowed in the NSG rule.
