INTRAWEB ACME

[Alexandre Machado]

the test is actually simple:

Can you connect to your application from an external address when it is online? Using HTTP?

You can check the name of the challenge file that IWCertManager saves into the C:\MyApplication\acme-challenge\ folder and try to retrieve it from your browser.

Let's say the file is named 123456789

Then you can try to as:

"http://yourdomain.com/.well-known/acme-challenge/123456789"

If you can't receive the file, nor Let's Encrypt can.

But it is important to use a machine that is outside your domain/network.
