WHMCS Order accept error (Array)

Hello,

I cannot get the WHMCS module to work. The order does not automatically create and when I go to manually activate it it throws an error with nothing but the word "Array".

I think it might be my API. The API seems to be trying to access itself from the static IP as when I click on one of the API functions it shows "https://192.168.0.150:2304..." I cannot access the api through my domain without it throwing a 404.

If I view the server api logs I get "unauthorized host"

try checking if your whmcs server ip is whitelisted in cwp api

Thanks for the response,

Im assuming I do that in the firewall?

They Ip is no different as they're on the same machine.

you would need to have on both hosts in firewall allow ip and also in cwp.admin in api configurationyou need to allow which ip can access api.
