The TCP connection MSS is set to 1460 bytes and also Don't fragment flag
is set. The server selects this MSS as a frame size on its side and
packet is dropped, probably. If you are using linux router try to use
this command "iptables -I FORWARD -p tcp --tcp-flags SYN,RST SYN -j
TCPMSS --clamp-mss-to-pmtu" or be careful to set MTU on all client
machines adapters correctly.
