I have a problem in the forum section when I click see all discussions, it gives me an error to try again later, and in the browser console it givse me this:
Mixed Content: The page at 'https://domain/courses/coursename/discussion/forum/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://domain/courses/coursename/discussion/forum/?ajax=1&page=1&sort_key=activity&sort_order=desc'. This request has been blocked; the content must be served over HTTPS.
There are no errors in lms, forum or nginx logs.
Somebody suggested to check forum config file, but I can not seem to find one, I know only lms.env.json and cms.env.json config files.
