When attempting to establish or test a hosting connection within your virtualization environment, the system reports an authentication failure with the following error message:

"The username and password combination supplied for this connection was not recognized."

This error indicates that the administrative credentials provided for the hosting connection are not being accepted by the hypervisor.

The resolution for this issue involves verifying and potentially updating the administrative credentials used for the hosting connection. Follow these steps:

1. Initial Error Confirmation:

   • The error is typically encountered when initially configuring the hosting connection or when testing an existing connection with the stored credentials.

2. Credential Troubleshooting:

   • Attempt Alternative Credentials: If you have access to other administrative accounts with the necessary permissions for the hypervisor, try testing the connection using those credentials. This step helps determine if the issue is specific to the initial username and password combination.

3. Issue Resolution:

   • Update Credentials: If alternative credentials work, or if you suspect the original password may have changed or was entered incorrectly, update the hosting connection settings with the correct username and password. Ensure that the username is spelled correctly and that the password is entered accurately, paying attention to case sensitivity.
   • Test Connection: After updating the credentials, test the hosting connection again. A successful connection confirms that the problem was indeed due to an incorrect username and/or password.

Problem Cause

The cause of the "The username and password combination supplied for this connection was not recognized" error when establishing or testing a hosting connection is directly attributed to incorrect administrative credentials being provided for the hypervisor. This can occur due to:

• Typographical errors: Mistakes during the initial entry of the username or password.
• Password changes: The password for the specified administrative account may have been changed on the hypervisor without being updated in the hosting connection settings.
• Incorrect account: The wrong administrative account might have been selected or entered for the connection.
• Account lockout: Although not explicitly mentioned in the symptoms, the administrative account on the hypervisor might be temporarily locked due to multiple failed login attempts.
