Would something like this help?
(borrowed from https://en.wikipedia.org/wiki/Path_MTU_Discovery)

"Many network security devices block all ICMP messages for perceived
 security benefits, including the errors that are necessary for the proper
 operation of PMTUD. This can result in connections that complete the
 TCP three-way handshake correctly, but then hang when data is transferred.
 This state is referred to as a black hole connection."


Best regards,
Ole
