That typically wouldn't block the connection.  The more usual
symptom when that happens is that the connection (i.e. the small
packet exchange at the start) succeeds but it subsequently hangs
when the first big data-bearing packet is sent.  I haven't
seen one of those happen for quite a while.

Getting a (tcp)traceroute when it is failing is probably the
best bet for identifying the problem.
