Business Central - check internet connection

GabrielMuzolf

Hi,
Is there any way to check if the Business Central OnPrem has access to the internet? Some method like IsNetworkAvailable():Boolean ?

You could do at HTTP GET on a public site like https://google.dk,
if you get a 200 OK then you are able to connect to other sites.

That was my idea as well to ping some public domain, but I was wondering if there is a better sollution, like a system codeunit with this kind of functionality.
Won't it work incorrectly if http request is blocked for our extension?

Yes it will, but you could add a few lines of code to check that with the HTTPResponseMesage.IsBlockedByEnvironment()

trigger OnRun()
    var
        Client : HttpClient;
        Response : HttpResponseMessage;
    begin
        if Response.IsBlockedByEnvironment() then
            Error('Please give access on extension management');
    end;
