This indicates that the problem is not in curl but in the network and
environment you use it in. Error 7 is CURLE_COULDNT_CONNECT which means that
the TCP connection failed to get established.

You should be able to wireshark the network to get further details about what
exactly happens and what doesn't happen when the failures occur.

Note that this is 14 releases and more than 2.5 years old. It might be worth
trying a more recent version. Even though I don't think the problem you see is
curl's fault.
