Can't connect to remote server

Hello

I'm getting an exception "Can't connect to the remote server"

when trying to access DataScope Select Rest API

I tried postman and it's working okay, but when I try it from our C# project I'm getting this exception

the url:

https://hosted.datascopeapi.reuters.com/RestApi/v1/Authentication/RequestToken

Exception:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.177.23:8080
