Remote user is connected in FortiClient through IPsec but no traffic to internal network

Hello,

We have an FGT 80D which was in FortiOS version 6.0.2, and been upgraded to version 6.2.0. After that, we noticed a problem in the remote user access through IPsec Tunnel, where access to the corporate network worked fine before upgrade, but now, it is not working correctly.

The FortiClient, says it is connected, but there is no ping or network share access.

I would like to know, what we can do to correct this situation.

Thank you in advance for your help,

Regards
