Pipeline not hitting server when tested through POSTMAN

I am testing my pipeline using on-premise secured URL from POSTMAN tool .When I am giving input using an AND condition e.g:(“Number = ‘999999999’ && Country = ‘US’”,) my on-premise secured URL is not hitting our azure server at all, instead it is saying “403ModSecurity Action” which occurs when the user is authenticated but isn’t authorized. However when I am running it using snaplogic elastic URL I am able to get the output expected.Also,when I am giving only one condition like "Number = ‘999999999’ it is working with our secured URL. Can someone please suggest what can be the possible reason for not hitting the server at all when using a combination in condition.
