Hello everyone,
reaching out to the community to verify if anyone is using OpenEDX in an IPv6 only or dual stack environment? We’re currently running dual stack and most of the services are working just fine when accessed using IPv6, the only issue we have is that file submissions are not working.
The POST request itself looks the same between IPv4 and IPv6: POST https://learn.our-url.com/courses/course-v1:OurOrg+MKSP-FAB+v1/xbl[…]m+block@problem1/handler/xmodule_handler/problem_check
This however returns a non-successful response:

}
The error message in there is Unable to deliver your submission to grader (Reason: cannot connect to server). Please try again later, however I could not find any error in the log files or any failed HTTP request in the browser tools. Anyone else using IPv6?
