Why I get the error "An unknown error has occurred" when I add a DirectAdmin server?

When I unchecked for don't use SSL for this connections everything works fine but I need to use SSL.

I tried disable CSF in target server and I get the same error.

How could I debug this?

Hi,

In order to see the commands being sent/received between WHMCS and the module, the Configuration > System Logs > Module Debug Log tool can be used
Please enable it, reproduce the problem, disable it again and then copy the data into this ticket reply for us to review.

More detailed instructions are published at http://docs.whmcs.com/Troubleshooting_Module_Problems

use ssh login to server.

type the following command:

/usr/local/directadmin/directadmin config | egrep "^ssl=|^cacert=|^cakey="

The result shows that ssl=0

Then type the followigh command:

/usr/local/directadmin/directadmin set ssl 1

Restart direct admin service

systemctl restart directadmin
