Re:How to clear "too many authentication failures " on port 22

Hi sonysutisna, 

It does look like the incorrect username or password was entered(or both). Did you enter the account information correctly? Have you ever successfully login using this account before? Are you able to login to XCC using the same account?

Please update the system firmware(UEFI & XCC) to the latest levels and try again.

Also, provide the server model and machine type for further assistance.

How to clear "too many authentication failures " on port 22

Re:How to clear "too many authentication failures " on port 22

Hi sonysutisna,

The "too many authentication failures" error usually occurs when there are too many failed login attempts via SSH. This is a security feature to prevent unauthorized access.

To clear this, you can restart the SSH service on your server. If you have root access, you can do this by running the following command in your terminal:

bash sudo service ssh restart

If you're still having trouble, it might be due to a problem with your SSH keys. You can try deleting your existing SSH keys and generating new ones.

Hi Sir,

Could you log in to the XCC WebGUI with the same/correct credentials? If the wrong credentials have been entered several times, the XCC will disable remote login access after reaching the maximum number of login failures.
