AWS Skill Builder sign in problem (Partner sign in)

I understand you're having trouble signing into AWS Skill Builder using the AWS Partner Network sign-in method. This is a common issue that can occur for several reasons.

For the "site temporarily unavailable" error that happens 9 out of 10 times, this could be related to:

1. Browser cache/cookie issues - Try clearing your browser cache and cookies
2. Try using your browser's incognito or private mode
3. Attempt to access from a different browser or network
4. Verify your device's date and time settings are correct (this can sometimes cause authentication issues)

Regarding the credentials issue when you do get past the first screen:

AWS Skill Builder typically uses AWS Builder ID for authentication, which is separate from your AWS Partner Central credentials. There might be confusion between the different authentication systems. When prompted for email and password, you should use the credentials associated with your AWS Builder ID, not your Partner Central login name.

If you continue to experience issues, I recommend:

1. Contacting AWS Training support directly through their support form
2. Checking with your organization's AWS account administrator to ensure your Partner Network access has been properly set up
3. Verifying that your device's time is synchronized correctly (even small time differences can sometimes cause authentication failures)

Since you're with a new AWS Partner, there might also be account setup steps that need to be completed before you can access all Partner resources.
