CLoud Shell access Denied

This is a common issue with AWS CloudShell that can occur even for accounts that aren't newly created, despite what the error message suggests about account verification.

Here are some troubleshooting steps you can try:

1. Wait a bit longer - although the message mentions up to two days for verification, sometimes it can take longer.

2. Try changing your AWS region and attempt to access CloudShell again.

3. Refresh your AWS Management Console completely.

4. You've already tried incognito mode, which is good. You might also try a completely different browser.

5. Check that your IAM identity has the necessary permissions to access CloudShell. The required managed policy is AWSCloudShellFullAccess.

If these steps don't resolve the issue, the most effective solution would be to contact AWS Support directly. You can open a support case under the "Account and billing" category. This type of support is available free of charge, even for users on the basic support plan.

When contacting support, be sure to mention:

• That your account is 10 days old
• The exact error message you're seeing
• The troubleshooting steps you've already taken

AWS Support has access to account-specific information that can help resolve this particular issue more effectively than community members can.

I’m having the exact same problem, how long did it take until it was solved and how did you fix it?
