OCSP status unauthorized (with 1.7.0 and earlier)

[lkarsten]

A server running hitch 1.7.0 is logging the following every 5 minutes:

Jan 16 10:39:43 hostname hitch[24465]: 20210116T103943.120223 [24494] {core} Error: OCSP response for cert /etc/letsencrypt/live/nnnn.no/hitch-bundle.pem has status unauthorized

What does it mean, and how do I fix this?

It appears for test domains that are possibly not being renewed. These are Let's Encrypt certificates. Is this hitch is trying to fetch an OCSP token/assurance for a certificate that has expired?

I have 300-400 of these in the log per day.

Can I somehow turn off OCSP stapling for some domains? I don't want to remove the test domains, even if they are expired currently. It is fine that they are, I just need to test varnish config changes by modifying my own /etc/hosts to point there temporarily. Going outside the TLS channel would void the test setup.

Any insight appreciated.
