OCSP lets clients check if a certificate has been revoked without downloading the entire revocation list.

Understanding OCSP
What does "OCSP Not Available" mean?
Some certificates don't include OCSP endpoints. This is completely normal for certificates with short validity periods
(like Let's Encrypt's 90-day certificates) since they expire before revocation would typically matter.
Is my certificate still secure?
Yes! The absence of OCSP doesn't affect your certificate's security. Modern browsers use multiple methods to check certificate validity,
including Certificate Transparency logs and CRL Distribution Points.
