I get this error message while converting a QVW document to Qlik Sense App:
"Conversion service error."
"The Converter tool server is not responding"
Do you get this error when trying to convert any QVW document, or is it a specific QVW that is failing?
What version of Qlik Sense are you running?
Is it possible for you to try this on a later version of Qlik Sense?
There has been a lot of improvements made to Converter Tool in later releases of Qlik Sense, both for Desktop and Server.
