How to validate from ordered and authorized about certes

[fszlin]

Would this work for you?

var authz = ctx.Authorization(Challenges.AuthzUri);
var httpChallengeInfo = await authz.Http();
await httpChallengeInfo.Validate();

Yes, but it throw error is:

Unable to update challenge :: The challenge is not pending.

[fszlin]

You probably try to validate the authz more than once.
Try opening the Challenges.AuthzUri in browser for more details.

I want to implement this process on my server:

step 1, get Token and KeyAuthz.
step 2. Users deploy authentication information. (.well-know/acme-challenge/)
step 3. validate and get a certificate.

e.g. sslforfree.com,

Can be provide some suggestions? thanks. ^_^

Sounds good, just watch for the rate limit if you are sending requests from server.

[BI7PRK]

If I understand nothing wrong, the rete limit is based on the domain name (account). It is not a server IP.

[fszlin]

Yes, you are right. I am hitting the account limit when I run tests.

In the development, use staging environment.
