d. My complete Caddy config:

vlc_service is a custom module build with xcaddy


{
        admin 0.0.0.0:37019
        http_port 37020
        order vlc_service last
        log {
                output file caddy.log
               
        }
}
127.0.0.1:37681 {
        handle /ws {
                vlc_service
        }
}

3. The problem I’m having:

When run in windows service, I got error:

{"level":"warn","ts":1673488997.9904804,"logger":"pki.ca.local","msg":"installing root certificate (you might be prompted for password)","path":"storage:pki/authorities/local/root.crt"}
{"level":"error","ts":1673488997.9946928,"logger":"pki.ca.local","msg":"failed to install root certificate","error":"add cert failed: Failed adding cert: The request is not supported.","certificate_file":"storage:pki/authorities/local/root.crt"}

4. Error messages and/or full log output:

5. What I already tried:

When I run caddy by hand on the same machine, such as caddy run --config Caddyfile,
And this method can install cert succesfully.
But When run as a windows service, It failed.

As I know, run as a windows service, may not be able to prompt dialog for trust cert.

This error do not affect caddy https , so it seems useless to solve this.
