I installed collabora code on docker and integrated it to my owncloud. My docker host is behind the firewall (iptables DNAT). When I try to open a document, I got error in my browser:
Content Security Policy: The page’s settings blocked the loading of a resource at http://my-domain.com/index.php/apps/richdocuments/WOPISrc=http%3A%2F%2Fmy-domain.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F2404_ocbi5fufi26w&title=New%20Document.docx&lang=en&closebutton=1&revisionhistory=1&permission=readonly (“frame-src”).
Could you give me a direction to solve the problem?
