Hello Marcos,

did you manage to solve this error.
I'm having the exact same problem...

*edit: I just found the problem. In connections I had given a port number for the proxy address.

Raf,

Can you explain what was changed to fix the issue?

Thanks,

Hello Sri,

In the connections where you have to give the proxyaddress I first also added a port number.

addressSmiley Tongueortnumber

but the proxyaddress should not contain a port number so I removed "Smiley Tongueortnumber".

After I did this the problem was solved for me.

Hi Raf,

Where would that proxaddress field reside?

I have a user who after adding more than 30 or so slides to the template editor received the same error message.

Thanks

Hello Michael,

Go to bullet point 9 in the following link:

https://help.qlik.com/en-US/nprinting/February2018/Content/GettingStarted/HowCreateConnections/Conne...

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.
