Can't display PDF located in a Beckhoff PLC on a TP600

Hardware and Linux

Hello,
We are trying to display a PDF on a TP600, thanks to the PDF viewer of TwinCAT 3 HMI.
Unfortunately, it doesn’t work properly, the page remains blank.
It works using another HMI or a web browser.
Have you ever experienced this issue ?

Maybe it due to security restrictions of the lighttpd.

In the config file at /etc/lighttpd.conf (I guess)
There should be an entry wich restricts to display content only from „own“ origin.

I can’t recall the exact name.

Replace/add this security config with the IP of the beckhoff device or „*“ from anywhere.

Hope this helps

After a few research it looks a Javascript component isn’t supported by the actual Qt WebEngine browser version…
