i got response code "0" for Rest API outbound call.

[ashishdevsingh]

I am trying to call Aws api from servicenow outbound. 
While sending the request body I am getting error code :0 without response body return. 
I have tried same thing in postman and it is working fine. 
now my query is: what should be the step to start debugging ? I tried to set logging level on but it doesn’t capture the fruitful message. 
any suggestions or step is appreciated. 
thank you!

Hi @Amit Verma ,

I am supscting this is because of some blocking at AWS side, so planning to use MID server. I will share the update if it works or not. however i am thinking why it is working from postman.

Hi @ashishdevsingh 

Can you confirm whether your AWS instance is accessible publicly over the internet or it is only accessible from the customer network ?

If the later, we need to route this REST API call from the mid server so that it succeed. Also, did you got any error logs ?

Thanks & Regards
