Unexpected Connection Errors

Hello -

I have a custom built website hosted through Amazon AWS with the domain and DNS control through GoDaddy. After I updated the nameservers to the Cloudflares given, my website was no longer accessible through Google Chrome. Just today, Cloudflare’s team got back to me with the following response:

Thank you for contacting Cloudflare Support. Very sorry for the wait time here: The cause of the ERR_SPDY_PROTOCOL_ERROR error is that there is a mismatch between the Content-Length header you are sending and the actual content-length.

I am not the most technical and do not have contact with my dev team for a few days. Is there anyone that can explain this to me in a way that I might understand and help me fix the issue?
