This solved the issue: Append to /etc/sysctl.conf the following: net.ipv4.tcp_mtu_probing = 1
after restart you should see at /proc/sys/net/ipv4/tcp_mtu_probing the value "1" A temporary solution is: echo 1 > /proc/sys/net/ipv4/tcp_mtu_probing caveat: this will be reset at boot. You can try also with value "2" if still not working.
