My blog started to use CloudFlare about 2 months ago, and all is going well. But recently we have been having the "Website Offline Message" a lot, so much so I had to remove CloudFlare.
I contacted the guys at CloudFlare to see if they can helps us so we can get back on board with them - their system is freakin' awesome!
What they have said is this:
"We were seeing a bunch of "connection reset by [your web
server]" and "Connection timed out" errors.
Jan 22 01:42:32 192.168.1.22 [nginx_error] 15m5: 2012/01/22 06:42:32
[error] 4492#0: *40639976 recv() failed (104: Connection reset by
peer) while reading response header from upstream, client:
220.127.116.11, server: 15c5, request: "GET
With a few other errors but they are either" 110: Connection timed out" or "104: Connection reset by peer". What is annoying is the site runs really fast, no one complains about the speed, just the fact that this error message appears too often - I even removed the "Available Offline Flag" from our settings in CloudFlare to make sure the message didn't appear, but it still did.
I contacted our host - ServerBeach, unmanaged, dedicated, Windows IIS7 - and they say they aren't blocking anything. Neither am I block any IP address in IIS. So am stumped. The files/pages that the error messages talk about seem to be fine as well when I browse to them.
Anyone got any ideas?
