Yes, same for me. Every few months some kind internet denizen points out to me that my certificate has lapsed, running it manually usually fixes it. LE software is pretty low quality, I've had multiple issues over the years some of which culminated in entire systems being overwritten by LE's broken python environment code.
If it's happening regularly wouldn't it make sense to add monitoring for it? E.g. my daily SSL renew check sanity-checks the validity of the certificates actually used by the affected services using openssl s_client after each run.
