We set up a REST API integration with our Acumatica account using Zapier and it works fine. We then tried connecting it to our sandbox account as well and it stopped working after a day. The error is that the connection timed out. We cannot connect from Zapier or web based Postman. Interestingly, we can connect from Postman desktop. The version on our sandbox account is 2022 R1.
Is there some sort of setting on the sandbox that is blocking the requests?
