I'm Currently using Magento 2.3.4 and have a WAF setup which essentially functions as a reverse-proxy, which means that the integrations will not connect due to the site pointing to a different I.P. address.
As a workaround the WAF provider (Sucuri) has suggested setting up a subdomain on the server which points to the correct I.P address and have the integrations connect through that instead.
I have set up the subdomain now but I am not sure how to get Magento 2 to connect the Integrations to the site through the subdomain rather than the primary domain.
Does anyone know which setting I would need to change to allow this to happen?
