playing around with OCSP stapling in HAProxy, I have issued quite a few OCSP requests in a short time. Now I get
$ openssl ocsp -sha512 -noverify -issuer chain.pem -cert cert.pem -url http://ocsp.int-x1.letsencrypt.org/ -header Host ocsp.int-x1.letsencrypt.org Responder Error: unauthorized (6)
Have I run into a rate limit or is there something else?
Edit: Also, what is the recommended interval for OCSP stapling? I was planning to run the script for all domains once per day.
