forticlient ssl vpn connected but no byte recieved

I'm trying to access some sites that are secured through forticlient VPN. I'm able to connect to VPN but the sites that I want to access are not accessible. byte received is 0. I've looked at log files. Config handler looks like why I'm having this behavior. I'm attaching the confighandler log if anyone can help me on how to correct this.

From the above information, I understand that you were able to connect SSLVPN and not able to access the internal sites, correct me if I am wrong.


Please check the below;

1) run the "route print" command on SSLVPN client command prompt and then check if the routing is published for your internal web site IP address, if it is published then try to ping that IP address from SSLVPN client

2) At the same time run the below command on FortiGate

diag sniff packet any 'host x.x.x.x and icmp' 4 0 l

(Replace x.x.x.x with your internal web site address)

Also you can run the below debug commands to check which firewall policy it is hitting

diag debug reset
diag debug enable
diagnose debug flow filter addr x.x.x.x

diagnose debug flow filter proto 1
diag debug flow show function-name enable
diagnose debug console timestamp enable
diag debug flow trace start 200

I have same issue.

The Forticlient program (7.0.6) works randomly, sometimes fine sometimes no.

No Bytes Received (0 KB).

Tests were made, with various versions and result is same.
