Question

SSL caddy with droplet

Created a fresh droplet and decided to test it with caddy to serve with https. Following this awesome article showing how to use caddy inside droplet. Everything went well up until step 4 (Enabling Automatic TLS with Let’s Encrypt).

Basically, when i did all the steps in the step 4. I go to my domain and received ERR_SSL_PROTOCOL_ERROR error.

Caddyfile

<domainname>.com.my {
    root * /var/www
    encode gzip
    file_server

    tls {
      dns digitalocean dop_v1_...
    }
}

/etc/systemd/system/caddy.service

[Service]
Type=notify
User=caddy
Group=caddy

Heya, @f4df2e98b9c74f7eb7f6a0629cf1c4

The ERR_SSL_PROTOCOL_ERROR error typically indicates an issue with the SSL/TLS configuration. - he Caddy logs can provide more detailed information about what is going wrong. Check the logs with the following command:

sudo journalctl -u caddy -f

Look for any errors related to SSL/TLS or Let’s Encrypt.

Heya,

Did you add your domain name in the config file? Also are you sure your domain is pointed to your Droplet?

Additinally, can you share your logs?
