Hello there,
I did setup one domain using custom SSL certificates by defining tls paths, but caddy is still loading the Lets Encrypt certs. Not sure if anything else to be configured. Below is the config added to load the custom certificates, please revert back with correct usage or missed out code.
xyz.com {
tls /etc/ssl/cert.pem /etc/ssl/key.pem
}
Thanks in advance,
Your certificates must have SANs which match the hostnames you have in your Caddy config. If the loaded certificates don’t have matching SANs, then Caddy will attempt to issue a valid certificate from a public issuer instead.

Thanks for reply.
But we had SANs on our crt but still it’s not loading on caddy.

Which ones? Post the output of:
openssl x509 -in cert.pem -text -noout
(I can’t remember if it needs to be in PEM or DER format for this.)

Thanks. That’s actually the wrong cert; that is for jb.abc.com , but you are serving xyz.com . The domains need to match.
Since I believe you have redacted the domain names, which is against our rules (and is mentioned in the help template that you saw), that’s about all the help we can give you without guessing. Please fill out the help template properly for further help.

@matt I am just hiding the original domain name and just replacing with pseudo names.

I know, but that creates problems when trying to help, since the actual values matter.

Ok, so the SAN matches. Now we know that’s not a problem, whereas before when you were redacting, it was actually a problem because they didn’t match.
Thanks.
This is a Let’s Encrypt certificate. What is the problem? Please fill out the help template.
