Make sure that your public key is not corrupted. Try generating a new public key and paste it in the backend.
Refer the following article to update the ssh gateway users public key.
Alternatively, you can update the public key by sshing into the gateway server and paste the public key in /home/user/.ssh/authorized_keys
