I’ll introduce troubleshooting for Amazon WorkSpaces “Unable to login” error that prevents login, and shows Unhealthy status in the AWS Management Console.

Background: Amazon WorkSpaces App "Unable to login" Error

I encountered an “Unable to login” error in the macOS Amazon WorkSpaces app that prevented me from logging in.

When I checked in the AWS Management Console, the status showed Unhealthy, so I’ll introduce how to resolve this issue.

How to Resolve Amazon WorkSpaces with "Unhealthy" Status

I performed troubleshooting based on the following articles.

• 異常ありとマークされている Windows WorkSpace をトラブルシューティングする (Troubleshooting Windows WorkSpaces marked as unhealthy)
• Reboot a WorkSpace - Amazon WorkSpaces

Reboot Amazon WorkSpaces

Reboot the WorkSpace.

If this doesn’t resolve the issue, reboot the WorkSpace from the Amazon WorkSpaces console. Wait a few minutes for the WorkSpace to come online, then retry connecting to the WorkSpace. The WorkSpace status will change within 90 minutes.

Amazon WorkSpaces Restore -> Rebuild

1. Restored and got an error
2. Rebuilt and login succeeded

That’s all from the Gemba.
