Thankyou Cyril, your patch fixed the connect issue.
Read timeout still seems a bit weird though, at settimeout(1), readtimeout
kicks in at about 4 seconds, and at settimeout(2), readtimeout kicks in at
about 8 seconds.
is that expected? I couldn't find read timeout explicitly set anywhere in
the same source file.
Thanks
Sachin
