Hi,
Our LDAP server is working before, but after we change our ISP the errors occurs (Can't contact LDAP server).
We can still ping our AD from firewall, and ping firewall from AD.

Hi Acxelsus,
You may verify the connection to LDAP server with the following command:
# diagnose sniffer packet any "host x.x.x.x and port yy" 4
Replace x.x.x.x to the LDAP server IP and yy to the LDAP port .
- verify the outbound interface
- verify if any response from the LDAP server
Please check if the following article relevant to your scenario:

Hi Acxelsus,
What is firewall firmware version?
You may try to run httpsd debug to check the LDAPS negotiation or you may try disable server-identity-check
config user ldap
edit xxx>>> Server Name
set server-identity-check disable
end
For httpsd debug:
# diagnose debug application httpsd -1
# diagnose debug enable
Test the connection again. To stop debug:
# diagnose debug disable
# diagnose debug reset
For your reference:
https://community.fortinet.com/t5/Fortinet-Forum/Cannot-contact-LDAP-server/td-p/90065
The firmware version is 7.0.5
Still the same, can't contact the ldap server
Please ensure the CA certificate is correct.
You may perform packet capture for the LDAP connection to get more detail.
