Hello, I'm having problem implementing ACME client. The challenge does not leave "Pending" and does not reach the domain's web server! I'm using the [acme-staging-v02.api.letsencrypt.org](http://acme-staging-v02.api.letsencrypt.org) url.ending! ---

Welcome to the Let's Encrypt Community, Cícero 🙂 Did you activate the challenge (by submitting a POST-as-GET to the challenge URL with an empty object as the payload)? ---

If you have correctly triggered a challenge, the associated authorization should transition to either "valid" or "invalid" in under a minute. ---

You should be repeatedly polling the authorization about every one second after triggering the challenge. Just looking at one response from triggering the challenge is useless. ---

I cut it after 10. Be certain to delay by a second between each. ---

If the authorization stays pending, you didn't trigger the challenge correctly. This is obvious if you look at authorization numbers in subsequent orders and see that they are the same as in previous orders. Authorizations (and challenges) get reused if they're pending. ---
