Document does not show when embedding

Hi all,

I did try this plugin on my testserver running on https:// and could embed an Excel spreadsheet without any problem.

When I tried to implement the same setup on my clients company internal server (https://) I could not get the plugin to work and show the Excel document correctly.

I am using Visual composer to add the sheet via “embed any document”. I would add a text block, click the “embed document” button, select the document and embed it. (https://prnt.sc/os4oha)

In case I select a file from media, nothing happenes, if I select file via url I receive the message “invalid url” although the url is correct-“ungültige url” (https://prnt.sc/os4ouj)

Please let me know if you know this issue and know how to fix it.

Thank you,
Max
