We can generate the certificate for domain with www, but not domain without www. It failed with http validation.

My domain is:

I ran this command: ACME client.

It produced this output: HTTP Validation failed, urn:ietf:params:acme:error:malformed: Unable to update challenge :: authorization must be pending

My web server is (include version): ASP.NET Server

The operating system my web server runs on is (include version): Ubuntu 22.04

I can login to a root shell on my machine: yes

The version of my client is: .NET dll certes.

How exactly? Can you please provide more context? E.g., the exact command ran or the code used.

Also, does certes provide debugging/verbose logging? If so, please also provide that.


It sounds like you are developing your own ACME client using certes as a library.

It sounds to me like you are trying to submit a challenge response for an authorization that has already failed.

Once they have failed you cannot re-try them, you have to either complete another authorization for the same identifier or start your order again.

If you can share your code it might help.
