It simply means that your remote web server was not able to accept the 
connection within 10 seconds.  You can increase the timeout with 
TIMEOUTconnect option.

Quite a huge load for a website.  You could try squid as an http accelerator 
or cluster your webserver.

I think you could get a bit better performance with: "connect = 10800" (same 
as "connect = localhost:10800").

I hope your xforwardedfor patch is not a security risk.  AFAIR there were 
obvious buffer overflows in the patches on stunnel.org website.
