Module not working over HTTPS only

[daum3ns]

The Module sets the document.url incorrect so that a "download failed" alert is seen:

https://api.onlyoffice.com/editors/config/document#url
i see in the logs that the url is set like humhub was plain-http although humhub is setup to use https. there is no way to set this in gui, nor in config files..

when i disable automatic redirect of http traffic to https for humhub, the module works ...

please fix this issue, or let me help you fix it! i think it must be quite simple, but i don't know the framework...
