Leaderboard <iframe> widget "refuse to connect"

[blahner]

I am trying to embed our CodaLab competition leaderboard into another website. I am using CodaLab's generated iframe, but I get the message on the webpage "codalab.lisn.upsaclay.fr refused to connect." (see attached image).

Specifically, here is CodaLab's generated leaderboard widget iframe code that is not working:
<iframe src="http://codalab.lisn.upsaclay.fr/competitions/leaderboard_widget/9304/" style="height: 500px; width: 100%; border: none;"></iframe>

I tried it with Chrome, Edge, and Firefox browsers. All do not work.
From what I can find online, it seems that the issue is the website desired to be in the iframe (i.e. CodaLab) has a Content Security Policy set to disallow their webpages from being included in iframes. Thus, the website (in this case CodaLab) would need to change their policy.
Can you confirm that this is the issue? If not, do you know any fixes? I appreciate your help!

Edit: Updating with new image of error message describing the root cause of the issue. Looking at this StackOverflow discussion, it seems that CodaLab would need to edit their IIS config file. Can this be done?

Good catch.

This seems to be a bug that appeared with the Python3 version of CodaLab.

We need to make some testing on our side. @dtuantran any thoughts on this?

It seems the iframe is still not working

@DeepDuke Thank you for reporting that the problem persists. Unfortunately, right now, nobody is working on this problem.

As CodaLab is an open-source community project, you are kindly invited to contribute if you think that you can find the source of the problem.
