I suppose it is a routing issue

If the session is a DNS session (port 53), and the response code isn't 0.

 

If the session isn't a DNS session, then the session received an ICMP packet with error code:

 

ICMP_DEST_UNREACH ICMP_SOURCE_QUENCH ICMP_TIME_EXCEEDED ICMP_PARAMETERPROB ICMP_REDIRECT

 

It is enabled for the session if the policy has traffic log enabled, e.g., set to logtraffic-all (have to verify).

make sure the system is actually online and that the Microsoft firewall is not blocking the response.
