thank your very much - yes, it is working, finally! I can open a document uploaded from a HTTP-scource in the viewer and in the annotation-tool!
That said, in the annotation-tool I get a message saying
“Uh-oh, something went wrong!
Error occured while sending request.”
after the content is loaded completely. I don’t´know if this is an serious error, but it will confuse my users, for sure. Maybe you can investigate this issue too, to make it perfect at last?
