Can not establish SSL VPN connection using fortiddns

I have followed the tutorial at the following link https://community.fortinet.com/t5/FortiGate/Technical-Tip-Configure-DDNS-for-SSL-VPN/ta-p/194137, but still cannot connect SSL VPN using DDNS.
I have followed all the exact same methods, but the error Unable to establish the VPN connection still appears. The VPN server may be unreachable.

Please give me advice, thank you.

Hi andribenjul,

 

Make sure the DNS record resolves into the correct IP address and that the IP address is reachable from the client.

 

Please take debug using below commands and share it here for checking:

 

diag debug reset
diagnose vpn ssl debug-filter src-addr4 x.x.x.x - Here x.x.x.x is the public IP of the user connecting.
diag debug appl sslvpn -1
diag debug appl fnbamd -1
diag debug enable

wait till the VPN disconnect, disable the logs by executing

diag debug disable
diag debug reset
