My recommendation is to get another hosting provider. Either one who knows how
to debug networks and local processes, or one who gives you a shell access so
that
you can debug it yourself. Asking for a help with debugging a blackbox on
a random mail list is the worst thing you can do.

So you are openning a TCP connection from a webserver process? That suggests
a lot. E.g. the operating system asserts a security policy that prevent from
that and as a result your program obtains ENOPERM or a similar error on the
connect() call. If it is a RHEL-based system, it will be caused by the default
SELinux policy.
