Broken PMTU discovery can cause this. PMTU discover can
be broken by stupid firewall rules which block all ICMP
packets as PMTU discover depends on ICMP packets being
returned when a packet with DF set would require fragmentation.


P.S. I would also send the log messages in future as sometimes
the self diagnosis is wrong.
