Ok this is either my code, socket.io or China. So I wrote DApp for my crypto project but for some reason our Chinese users have problems using it... So i dig through our code for HOURS! and finally resort to making an AJAX call from the client to a hideous PHP script for logging and what do i find?

For some reason the WebSocket cannot connect. I haven't mapped this so it's only conjecture but I think the GFW is blocking my users connections? (Also using a VPN seems to fix it)

Anyone else had this issue?

    That is very much possible. One of our clients' websocket connection wasn't successful when we went through our corporate WiFi. The moment we switched to our mobile hotspot, it worked. Pongs are required for the connection to be established and they could very well be blocked for any reason
