It’s Devs, all right? I need your help regarding an error I am taking when consuming the Endpoint of an API via Httpclient with Postasync() and Wait() methods from a Webservice hosted on another server. The exception is the: "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 XX.XXX.XX.XXX:443". The target API is on an HTTPS domain so the IP port is 443. Searching on the subject I tried several solutions like: 1 check if the port is free on IIS, 2 checked the rules of Firewall, 3 checked the Proxy, 4 also checked if the certificate of security of the API is valid on the server from where the call is starting (web service server) and finally pinged the API URL on the server hosting the client.
Do you have any other idea or possibility of the cause of this exception?
Personal vlw!
