Unable to login to Lightsail: "There seems to be a problem with your session. Please try again in a few minutes or login again. If the problem persists try clearing your browser cookies."

Hello AWS Community,

I am experiencing a persistent issue accessing AWS Lightsail at https://lightsail.aws.amazon.com/ls/webapp/home, despite being able to log in to the main AWS console (console.aws.amazon.com) without any issues.

1. Logged in to https://us-east-1.console.aws.amazon.com/console/home?region=us-east-1# successfully.
2. Clicked on the "Lightsail" icon
3. When attempting to access Lightsail, I encounter the following error message:

There seems to be a problem with your session.
Please try again in a few minutes or login again.
If the problem persists try clearing your browser cookies.

Steps I've Already Tried:

1. Cleared browser cookies and cache.
2. Attempted access using multiple browsers (Chrome, Firefox, Safari).
3. Changed network environments, including switching to a phone hotspot.
4. Disabled ad blockers and similar extensions.
5. Switched DNS settings.
6. Attempted logging in and out, and also tried switching AWS regions within the AWS console.

Additional Information:

• I have verified that the AWS service health dashboard shows no current issues with Lightsail.
• The problem persists across all AWS regions in the US.

Request:

Could anyone please provide insights or further troubleshooting steps I might consider to resolve this session issue with Lightsail? Any advice or shared experiences with similar issues would be greatly appreciated!

Thank you in advance for your assistance!
