Failed to create account using cyberpanel whmcs Module

Cyberpanel Whmcs Module Test Connection failed and also i could not create users from whmcs, but also i can login directly from whmcs.
I have entered Ip address as host name , user id and password.

Error is : Order Accept Encountered Problems

Not gonna work, WHMCs and Blesta modules are a bit useless, CyberPanel: manual set up. I do not even know why they have been created, it will just not work.

Blesta module works fine with cyberpanel…its the one billing module that is problem free for me.
