The underlying connection was closed: The connection was closed unexpectedely
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 unexpectedely" i 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)
This shows you the screen where you set up your connection to the qlikview or sense server. You will see in the screenshot that you can enter a proxy address. Make sure this address doesn't contain a portnumber.
This solved the errors for me when trying to add charts to a powerpoint.
