I just tried to play my own game in class ( hosted on Itch Io with iframe to my site) 

It is throwing up loads of secruity warnings. wont let me access anythign Itch IO - forum , dashboard or anything. 

anyone else have or had this issue. 

I went on a VPN to try it on thialand, singapore, uk etc and it worked. 

I think the school block it, i did some test and it seems like itch.io works on china
