Changes related to Let’s Encrypt on Expressway-E

Help

Hello, Team
From official sources, we have received information about upcoming changes in the operation of Let’s Encrypt certificates that may affect the functionality of our infrastructure.

Let’s Encrypt certificates are used on Expressway X14.3.7
(ISRG Root X1 is installed in the Trusted CA certificates, and R12, R13 are used as Server certificates, which are updated via the ACME Certificate Service).

Questions:
How will the planned changes in the Let’s Encrypt certificate issuance process affect the operation of Expressway?
What potential risks are associated with these changes in the certificate issuance process?
What recommendations does Cisco provide in the current situation regarding the use of Let’s Encrypt certificates in the Expressway cluster?

That really sounds like a question for Cisco, doesn't it?
