Unable to call streaming API on sandbox
Hi I created a HTTP api source connection on AEP sandbox and when i tried calling via postman. I always get the following error "

I cross checked the settings and can see that the inlet id exist in AEP

I have one other sandbox of a different client and the same steps work there. I am not sure what wrong i am doing here.
Just for info, i am currently trying this on B2B instance of AEP.
