So i was able to resolve this issue. Few things to try to create CloudShell environment:
Time Synchronization: Make sure Your machine time is accurate. It means its correct based on world time. did you try from another machine to see if its working there? may be any time sync related issue?
Check in different regions..
check AWSCloudShellFullAccess policy to ensure it has below JSON data.
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"cloudshell:*"
],
"Effect": "Allow",
"Resource": "*"
}
]
}
Your account must be verified before you can add new CloudFront
resources. To verify your account, please contact AWS Support
(https://console.aws.amazon.com/support/home#/ ) and include this
error message.
Click the support link
Navigate to:
Support / New case / Service limit increase
Limit type:
CloudFront Distributions
In Requests select:
Limit: Web Distributions per Account
New limit value: <TYPE_YOUR_NEW_VALUE_HERE>
MY CASE: In my case, I had 2 distributions, wanted to create 3rd, but couldn't. So I have put as <TYPE_YOUR_NEW_VALUE_HERE> a number 10.
Note: If nothing works choose last option as your last resort to confirm your account is verified.
