Let's Encrypt sets date for ending OCSP support

In July, Let's Encrypt announced it was ending
support 'as soon as possible' for the Online
Certificate Status Protocol (OCSP) in favor of Certificate
Revocation Lists (CRLs) due to privacy concerns. The organization
has now announced
that it has set a timeline, and will be turning off its OCSP
responders on August 6, 2025. There is additional action required
for Let's Encrypt users who use the OCSP Must Staple Extension:

As of January 30, 2025, issuance requests that include the OCSP
Must Staple extension will fail, unless the requesting account has
previously issued a certificate containing the OCSP Must Staple
extension.

As of May 7, all issuance requests that include the OCSP Must
Staple extension will fail, including renewals. Please change your
ACME client configuration to not request the extension.
