FortiClient 6.4.3 no local DNS

Hi, I am using FortiClient version 6.4.3 and VPN Fortigate 100f. The problem is, after I find it, I can't find my local site names. If he enters the IP address, I go to the website without any problem. Nslookup also solves correctly, but after typing the address in the browser, I have a message that the page was not found. On VPNw ssl-vpn settings I have correct DNS names. Is there a problem?
