playing with the staging CA. I’m doing frequent requests - a complete cycle - nonce, order, authz, check, finalize, download.
Interestingly, the challenges don’t seem to be checked but authz-s are set as valid when checked after my validation timeout expires. I checked that in my “web server” and in Nginx logs - which fronts my server as a reverse proxy. And neither shows any incoming requests.
Are there any circumstances when the LE RA can decide to skip the challenge validations?
UPDATE: before you read on, it all works fine. I just didn’t expect that the authorizations (authz) can be re-used while they are valid.
