MergeCertificate The given header was not found

[itsins]

Hello,

I do get the following Error when trying to issue a certificate:

Exception while executing function: MergeCertificate The given header was not found.

The Certificate is successfully created on our registration authority and then downloaded (according to the logs) in order to get merged with the Certificate created in the acmebot keyvault. The merge process then fails with the message above.

When I do merge the two certificates together manually, the whole process can be completed without any errors and the certficate is then displayed in the dashboard.

Can you might help us to identify the cause why the merge certificate activity failed?
Feel free to contact me if you do need any more information from my side

Thank you very much

Thanks for the feedback.

It appears that this issue is occurring because Acmebot assumes that a specific Header is always present when retrieving certificates.

That header does not appear to be required by the ACME specification, so we will be fixing the Acmebot implementation.

The problem has been fixed in the latest v4 release. I believe that upgrading an existing Acmebot to v4 using #500 as a reference will resolve the issue.

Hello Tatsuro,

I can confirm that the newest version is working fine now.
Thank you very much for your support.
