Authentication Failed

Hi I'm trying to log in to a remote university server using my credentials, but I get an "Authentication Failed" message. The following is the related log file. Any idea how I can solve this?

Re: Authentication Failed

If you have problems authenticating to a server, you better contact server administrator.

Unless you are able to login using any other SSH/SFTP client.
