The destination website tests perfectly and is on the same web host and IP address but for some reason the source site started showing these issues when we changed IP.(same host but new plan).

Example below:

Array
(
[0] => Array
(
[headers] => Array
(
[server] => hws
[date] => Sat, 08 Nov 2025 02:38:09 GMT
[content-type] => application/json; charset=UTF-8
[vary] => Accept-Encoding
[x-litespeed-cache-control] => no-cache
[cache-control] => no-cache, must-revalidate, max-age=0, no-store, private
[platform] => hostinger
[alt-svc] => h3=”:443″; ma=86400
[x-processing-time] => 0.318
[content-encoding] => br
)

        [response_code] => 200
        [response_message] => OK
        [body] => {"success":false,"data":"The remote website encountered the following error: Unauthorized access (invalid remote IP address xx.xx.xx.xxx) - https:\/\/ourwebsite.com"}
    )

)
