Hi @ all,

I'm using the trial-version of the latest Cerberus FTP and tried to share a File or Folder for public up-/download via link or mail.

After clicking "Share" I get die Error "Client-provided host information failed validation. Please contact your system administrator."

 

Any hint what I am doing wrong? SMTP is working, using the Common Mailadresse, not the personal Mail.

 

Best regards

Franz

  Hello Franz,

  This is a newer security feature in Cerberus FTP Server designed to prevent against a type of attack know as a host header attack.

   

  Check out this link for details on how to configure the domain allow list for you server:

   

  https://support.cerberusftp.com/hc/en-us/articles/360010400559-Why-are-my-users-getting-errors-when-resetting-passwords-or-creating-public-shares-after-I-upgraded-to-v11-0-or-v10-0-17

   

  Basically, you have to add your public domain to the Client Domain Allow List edit box.

   

  Example:  If the public URL to your Cerberus server is https://sftp.my-cerberus-server.com then you will need to add sftp.my-cerberus-server.com to the allow list.
