  • Hi ProK


    Please provide us with more details when you experience such error: like “MDC-correlationId” response header value, which is sent as a response header from our server and also the date/time when it happened.

    It might be also helpful to increase the verbosity of output (e.g. --verbose flag in certbot) to detect errors.

      Andriy Mahats Thanks for your response. I checked and found that issue was related to IP Buypass uses to validate the http-01 challenge. It has changed and I had not allowed that one on my firewall.


      Issue has been resolved now. But, I would like to suggest that; in-case Buypass server not able to validate the challenge, more elaborated error response/error code/ error message should be there in Certbot.

      What are the IPs of  http-01 challenge? Are they


      IPv6: 2a03:520::/29


      Or different ones?
