Unable to Establish VPN Connection and stuck at 10

Hi Syed

10% could mean you are not even reaching the remote VPN IP:port.

You can try from web browser with https://IP:port to confirm if it is reachable or not.

Yes when i do https://110.38.225.213:4321 it redirect me to login page, telnet is also successful, I have other pcs connected to same network, connect to the VPN easily,I cant

is your device able to ping the remote gateway or if the remote gateway used is an fqdn, are you able to resolve the dns of it? Check whether the configured sslvpn port on your FortiClient is correct or not.

Run these debugs on your Fortigate and reproduce the issue:

> If you do not see any relevant sslvpn debugs on the Fortigate, there is a high chance that the packets from your device are not even reaching Fortigate in the first place.

diag debug console timestamp enable
diag vpn ssl debug-filter src-addr4 x.x.x.x ==> x.x.x.x should be the public ip of the client that is connecting: whatismyip.com
diag debug application sslvpn -1
diag debug application fnbamd -1
diagnose debug enable

-> Reproduce issue

Disable debug:

# diag deb dis

diag deb reset
