Dnf issue with OCSP check / TLS cert

Rocky Linux General

It seems that the OCSP check does not work reliable? Anyone seeing this?

# LANG=C yum update  --refresh

An Let’s Encrypt infra issue?

I found out that our infra has sslverifystatus for all repos enabled. Until now, this never was a problem. I wonder who could address this issue, as OCSP is a common measure. mirrors.rockylinux.org is hosted by Fastly and OCSP status is normaly provided by the TLS terminating server (>Fastly). Any hints?
