absolutely. there are any number of reasons Caddy would be unable to renew the cert, just off the top of my head:

- LetsEncrypt has downtime or unavailability

- If you're doing dns-01 challenges for LE, whatever cred Caddy uses for that might expire / become invalidated.

- disk fills up (or gets unexpectedly remounted read-only) and Caddy is unable to write the renewed certs
