Students are unable to access Sketchup for Schools

Hi,

I may be having the same problem as the user in a previous forum, but I cannot find the answer to the fix. When students try to log in to sketchup for schools on a chromebook, they can get to the login portion, then it sits at the loading screen and will not move past that. The post in question mentions that there is an issue with a proxy.html integration, which makes sense because our content filter blocks proxy sites. Is there a viable way to fix this without unblocking all proxy sites?

Thanks,

Kyle
