Plesk Plugin error because of being in the beta?

I get this error when i try to use the plesk plugin to get a certificate for my website:

Fehler: Let’s Encrypt SSL certificate installation failed: Failed letsencrypt execution: 2015-12-05 12:19:33,295:WARNING:letsencrypt.cli:Root (sudo) is required to run most of letsencrypt functionality.
Failed authorization procedure. (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from []: 401

  • The following ‘urn:acme:error:unauthorized’ errors were reported by
    the server:

Error: The client lacks sufficient authorization

how can I fix this?
