UNABLE TO ACCESS MY EC2 INSTANCES IN US-EAST-1 REGION

0

Good day, I had in the past been using us-east-1 region for all my testing workload and I had no issues, but recently I have not been able to access all the new ec2 instances I create, even via the default VPC.

But today when I moved to another region us-west-1, I discovered that I am able to access any ec2 instance I created via instance connect and the web browser.

Please does anyone know the reason for this anomaly?

Thanks

Hello.

What kind of access would fail?
Also, what error do you get when connecting?
Are the necessary communications allowed by the inbound rules of the security group set in EC2?
Also, is the route to the Internet gateway set in the route table of the subnet where EC2 is running?

Please also check the following documents.

  • This was the error that I was getting 'ssh: connect to host ec2-34-204-5-151.compute-1.amazonaws.com port 22: Connection timed out' when using a custom VPC that I created in the us-east-1 region, hence I decided to use the default VPC, and it still failed to connect. Based on the above scenario, I decided to move to us-west-1 and I was able to connect using the default VPC. After I read your response. I decided to go back and retry the process in the us-east-1 region, using the default VPC and it worked. Not sure if my ISP had anything to do with it.
