Windows Azure Endpoint not working

Question

I have a problem with my windows azure virtual machine. I need to open the Port 443 (HTTPS) on the VM. In the Endpoint Config. of the virtual machine, I opened it and configure the ACL with the following parameters:

Permit
0.0.0.0/0

It's a Windows Server 2012 VM and I created the firewall rule for the public Connection. A Port Check from ping.eu shows that the port 443 is closed.

The Location of the virtual machine is Western Europe.

I hope, you can help me.

Kind Regards Sebastian

I wonder if it's the ACL rule. By default an endpoint is open and only when you add a rule does it lock down. Have you tried removing the ACL rule? — Luke Merrett
I've got the same problem - endpoint open and firewall rule set on vm but still cannot get through. Did you even find a solution? — Jon

I also had this issue and it was very annoying! I thought at first I was not setting up the SSL bindings correctly or that it was a certificate issue, then moved on to firewall issues. In the end it was the Azure endpoint at fault.

I had added the 443 endpoint, disabled local firewall and got nothing nothing. I got suspicious when I added a new endpoint on 8080, bound to https and it worked fine.

I deleted the 443 endpoint, shut the Azure VM down from the webinterface after shutting down the client. Created a new 443 endpoint and restarted the VM (I had already tried restarting my win2012r2 vm). It worked.

It must be a glitch in the networking stack of azure endpoints. You are not going mad!!

Hope that helps! P
