The cert was renewed recently with a deprecated validation method and therefore needs updating. I’ve received one email like this before for a different domain on a different server, but couldn’t find my notes, so decided to publish them here so they can be found by other people. Hello, Action may be required to prevent your Let's Encrypt certificate renewals from breaking.
