Caddy logs not showing up

1. The problem I’m having:

I’m using Caddy API to load JSON config.

{
  "admin": {
    "disabled": false
  },

                      ]
                    },

                              "{http.request.uri.path}/",
                              "/index.html"
                            ]
                          }
                        }
                      ]

                        }
                      ]
                    }
                  ]
                }
              ]
            }
          ],
          "logs": {}
        }
      }
    },

            "on_demand": true
          }
        ]
      }
    }
  }
}

A domain pointed to the server is not generating SSL certification. I need to check the logs but can’t find any log file in /var/log/caddy directory, even there is no caddy directory in the $HOME/.local/share/ directory.

5. Links to relevant resources:

The logs are printed to stdout/stderr. It depends how you’re running Caddy where that will go. See Keep Caddy Running — Caddy Documentation for more details.

Caddy is running using the Caddy API /load/ method, no other configuration is done.

sudo service caddy status gives

Active: inactive (dead)

But how did you start Caddy in the first place? Clearly it’s not running as a service because your service is inactive (which is not a good thing – you really should run Caddy as a service).

And please completely fill out the help topic template, as per the forum rules. There’s a big lack of information here, so we can’t do much to help.
