Http challenge failure

My domain is:
support.crypshark.com

Aceme account url:
https://acme-v02.api.letsencrypt.org/acme/acct/608488156

I am using acme4j java client

Problem:

  • We are using above mentioned acme java client

  • For few domains the http challenge failed for us. We have retry mechanism running after 6 hours it got passed in those retries.

  • I wanted to know why it would have failed so that we can make our system more robust.

  • For the mentioned domain it was failed at 2022-10-30 17:39:49 UTC. There is no error codes, nothing in the http challenge.

  • The http request initiated for the challenge is also responded with 200 response code from our infra. This is the url from our logs http://support.crypshark.com:80/.well-known/acme-challenge/WYIbJ1jGmeYVzRuoj4IxqEgv2bTddFEvrDPNTknxrUA

Can you please help on this, knowing the reason for failure so that if any changes required on our side, we can do those?

Thank you.
