I'm creating a central control add-on for business where I need to call other web services. I'm using AL's HttpClient class for this, but no calls are successful.
The call is finished in 2.5 to 3 minutes. Although the HttpStatusCode is "200" and the ResponseText is "OK," the call always fails and enters an error handling block.
Observing the reply while Response.Content.ReadAs(responseText); dynamic error message is produced.
What am I overlooking? I attempted the sandbox and on-premises installs of the newest 2019 after having already allowed external access in extension management.
I have found related link which you can go through it or either it may help you:-
