1. The problem I’m having:
I try to get a certificate for a specific subdomain while also using a wildcard certificate.
I have a wildcard domain, lets say *.example.com
I can get a wildcard certificate for this, works perfectly with Caddy.
Now i have a subdomain sub.example.com and i want Caddy to not use the wildcard certificate but to get a certificate for sub.example.com
The relevant part of my Caddyfile looks like this:
sub.example.com {
tls {
issuer acme
}
reverse_proxy 1.2.3.4
}
*.example.com {
reverse_proxy 1.2.3.4.5
tls {
dns ionos ...
}
}
The Caddy Documentation says i have to explicitly configure to get a certificate for my subdomain:
Blockquote
As of Caddy 2.10, when automating a wildcard certificate, Caddy will use the wildcard certificate for individual subdomains in the configuration. It will not get certificates for individual subdomains unless explicitly configured to do so.
I just can’t find any documentation on how to do this. And my configuration does not work, if i open sub.example.com in the browser i can see that the certificate is for *.example.com
Would be great if someone could tell me how to do this the right way.
