I tried it, it looks like the Socket.OSSupportsIPv6 returns true, so it attempts to create an IPv6 socket and that is what throws an exception. �Any thoughts on what I can do at this point?<div>Thanks<br><br><div class="gmail_quote">

which, on the surface of it, suggests that your system is unwilling to let the client speak IPv4. Can you think of a reason why that would be the case?<br>
<br>
I suggest sticking that line into a mini program of its own, to see whether that fails too.<br>
