Please try to be more careful with how you format your posts. Code blocks start and end with triple-backticks, i.e. ```, and they must be on their own lines. If you don’t properly terminate a code block, it eats up the rest of your post, making it very difficult to read.
“latest” is not a version. Please find the actual version of Caddy you’re running. The latest docker tag does not necessarily mean you’re running the latest version, because it’s dependent on you continually pulling the latest version down from Docker Hub to update it.
You can run docker-compose exec -w /etc/caddy caddy caddy version to get the version from your running Caddy container.
It seems like your ACME account is broken, for some reason.
You can try wiping out the data from your /data volume to have Caddy re-issue all the certificates again, using a new ACME account.
This one’s weird though. Caddy is failing to connect to ZeroSSL. Unfortunately the error message is not much help, but it’s failing to complete the TLS handshake. It could be that ZeroSSL had downtime at that time though, they don’t tend to have 100% uptime unfortunately: https://status.zerossl.com/
