"Connection Reset", "No data recieved" all of the time on my website

Many people appear to have this problem on Godaddy hosting and Godaddy have told one complainant this

It is possible that when the error is occurring that it is triggering the Mod_sec of the hosting account. In the current hosting account type that you have it isn't possible for us to disable that function for security reasons. We do have hosting accounts with cPanel that allow us to bypass the Mod_Sec rules, which could resolve the issue.
