Hi thanks so much for this!

I have an issue trying to deploy this in Azure and using it with zerossl.

1.) I've verified IAM permissions for the resource groups required.
2.) Azure DNS is configured, IAM permissions granted and added Application Configuration for Acmebot:AzureDns:SubscriptionId
3.) For ZeroSSL since it requires EAB; I added Acmebot:ExternalAccountBinding:Algorithm(tried HS256 and HS384), configured Acmebot:ExternalAccountBinding:HmacKey, and Acmebot:ExternalAccountBinding:KeyId. The Acmebot:Endpoint is https://acme.zerossl.com/v2/DV90/.

When I try to issue a new certificate I get this

"Orchestrator function 'AddCertificate_Orchestrator' failed: The orchestrator function 'IssueCertificate' failed: "The activity function 'UploadCertificate' failed: "missing header: Replay-Nonce". See the function execution logs for additional details.". See the function execution logs for additional details."

Function 'UploadCertificate (Activity)' failed with an error. Reason: System.Exception: missing header: Replay-Nonce

Renewing also doesn't seem to work.

Any assistance you might be able to provide?

Thank you!
