"xd.adobe.com hast declined the connection." "xd.adobe.com hat die Verbindung abgelehnt."
I'm trying to embed an XD prototype into a website via iframe for a client. I embedded it a few weeks ago and it worked fine, now I changed something in the XD document, updated the link and I have the error message: xd.adobe.com hat die Verbindung abgelehnt. (xd.adobe.com hast declined the connection.) and can't see the prototype. I've tried it from various computers and networks, did all the troubleshooting from this article: https://helpx.adobe.com/x-productkb/multi/troubleshoot-cant-connect-online-service.html and tried to embed it in another website as well; always the same error. Please help!
