Cause

The issue occurs if there is a backslash (\) character in the vMA password.

Resolution

To resolve this issue, ensure the vMA password does not include a backslash character.

To change the vMA password ensuring there is no backslash character:

1. Connect to the vMA console in a vSphere Client.
2. Press Alt + F2 to access the login prompt.
3. Enter vi-admin for the user and enter the current password.
4. In the command-line, run the command:
   
   passwd
   
   
5. When prompted, enter a new password that does not include a backslash.

Additional Information

For more information, see the vSphere Management Assistant Guide.

To troubleshoot SSH issues on the vMA:

1. To determine if the sshd service is running, run the command:
   
   # sudo service sshd status
   
   
2. If the SSH service is not running, restart the service using this command:
   
   # sudo service sshd restart
   
   
3. If the issue persists even after restarting the service, open the /etc/hosts.allow file and change the sshd: ALL entry to:
   sshd: ALL: ALLOW
