The first suggestion was almost correct. The client page was reading one
cookie and trying to set a session state cookie. 

Big thanks for the help!

This question is hard to answer without knowing more
about how you are setting and reading the cookie.
One possible problem is that  on the client page your
browser is actually trying to replay two cookies -- the
one you are testing and some other one that you
set previously (and that previous cookie is the
one getting blocked). Another possible problem
is that the cookie may sometimes be replayed in
a first party context and sometimes in a thirdparty
