Getting error : getaddrinfo ENOTFOUND while calling RBA API web service

I am new to using postman for API calls. I’m trying to access via postman but receiving error message as below.
Error: getaddrinfo ENOTFOUND

I have been provided with a client certificate which I have added in postman. I feel like the request fails well before reaching the client certificate validation. I’m able to access the same URL via Chrome and get a response after adding the client certificate (.p12 file) for my user.

I tried to access the wsdl file by but received the same error message as well , chrome gives me the wsdl contents.

I appreciate your time and look forward to the community’s response.
