unable to connect aws ec2 from vnc viewer or ssh

[#1]

Hello Friends,

Please help me on this.

I have set up aws ec2 instance for hdpcd practice exam. Also, I have downloaded vnc viewer.

Now, as per document I am able to start ec2 instance. The region which I have selected is Asia Pacific - Mumbai. I am using public dns name with port 5901. Also, I have disabled my windows firewall.

But when trying to connect from VNC Viewer, it is showing unable to connect error message. Please suggest how to get it through.

Unfortunately, I tried to take help from one of my friend who did this on his own machine.

Even, he is not able to help me out.

Thanking you

Did you create a FW rule in you ec2. Console to allow port 5901 to outside world * or limited it to your IP?

Please revert

Thanks Geoffrey for your response.

Yes, I did that and now the issue is resolved.

It seems, only the EC2 instance of N.Virginia region works fine for hdpcd practice exam. Not sure about the reason.

But when I changed the region from drop down and created a new instance, I was able to connect from VNC Viewer.

I hope that problem will not appear again. If so then I will reach out to you guys.

Thanking you
