Here is a list of free french proxy :
Can you test with it ?
When I tested 22.214.171.124 3128 was up and I can access to the site.
Maybe you know a free VPN to access...
I join an image with screen captures and some explanations in the bug report.
When testing I saw that only videos in "Info" theme work. All others and live ("direct") stream do not work.
It is difficult to give you more informations.
I hope you will reproduce using a proxy.
