      Hi Dear Qlik Community

       

      I was working well with the customer Qlik NP Installation, but from yesterday the Preview Designer Report, show me this error Message "The underlying connection was closed: The connection was closed unexpectedelyi tried this steps to solve the problem

       

      1) Backup a PostgreSQL DB Repository

      2) Uninstall Qlik NP Server, Qlik NP Enginee and Qlik NP Designer (Without delete NPrinting Folders on ProgramData Folder, User AppData Folder adn %Temp% folder)

      3) Uninstall Earlang

      4) Qlik NP Server, Qlik NP Enginee and Qlik NP Designer

      5) Restore the backup PostgreSQL DB Repository


      I attached the Logs and Print Screen error message
