I met the same problem, and after 1 day's stucking, here is my solution:

Assuming the site name is: site.com, and I want caddy handle these domains for me:

• a.dot.site.com

• b.dot.site.com

• c.dot.site.com

• a.eth.site.com

• b.eth.site.com

• c.eth.site.com

1.make sure you set SSL access available. e.g. via cloudflare:

2.set the A address pointing to your Caddy server's IP.

2.Caddy file should looks like:

# the key is: you have to list all the patterns for your multiple subdomains
*.site.com *.eth.site.com *.dot.site.com {
  reverse_proxy 127.0.0.1:4567

  log {
    output file /var/log/access-wildcard-site.com.log
  }

  tls {
    dns cloudflare <your cloud flare api key>
  }

}
