Flow closed by inspection

[bgl-group]

I have a problem with a customer trying to reach a server pbo-prd01 in our network over a VPN from ip address 'cust-prd01'where the packets seem to be dropped by 'Flow closed by inspection'
What does this mean and how can i fix it?

The IPS sensor in the firewall is switched off.

cust-prd01 18580 pbo-prd01 1860 Teardown TCP connection 17266 for External:cust-prd01/18580 to Inside:pbo-prd01/1860 duration 0:00:08 bytes 11007 Flow closed by inspection 
cust-prd01 18580 pbo-prd01 1861 Teardown TCP connection 17268 for External:cust-prd01/18580 to Inside:pbo-prd01/1861 duration 0:00:07 bytes 8847 Flow closed by inspection

In only see icmp error inspection configured.  Opening a TAC case sounds like a

good idea at this point.
