ACME V2 error: HTTP 406 Not Acceptable

Hi,

I developed 3 ACME clients for less tech-savvy users. Two do automation on shared hosting (issue + install SSL). One of them listed on the Let's Encrypt website. One is listed on the WordPress plugin directory.

Today I tried the WordPress plugin with BuyPass ACME V2. Everything went smoothly except for the last step where the client sends a signed request to the finalize URL to get the certificate. Here I am getting 406 not acceptable error (with both staging and production). Complete BuyPass ACME response is given below.

Array
(
    [code] => 406
    [message] => NOT_ACCEPTABLE
    [details] => HTTP 406 Not Acceptable
)

However, I am getting the certificate location too. I have to download the certificate manually and installed.

Could you please help me find out where I am doing wrong?

Domain name: staging5.speedify.tech

CentOS

PHP 7.0

WordPress 5.4.1

I run the PHP script with cron job.

 

Thanks!

  • Hi Anindya

     

    It looks that there is a content negotiation issue on the endpoint to download the certificate. According to https://tools.ietf.org/html/rfc8555#section-7.4.2 the default format for certificate is application/pem-certificate-chain.

     

    The cause of this error might be that the certificate format, requested in Accept header of the HTTP GET request, is different than application/pem-certificate-chain. We do support also application/pkix-cert format.

     

    If the “*/*” is specified as the Accept header value, then the cert will be returned in default format. To request the cert in application/pkix-cert format, the value “application/pkix-cert” should be set explicitly in the Accept header.

     

    Regards,

    Andriy
