Disabling TLS
By default, Caddy will attempt to automatically set up TLS and HTTPS. When attempting to initially set up a server, however, you may want this disabled.
References:
# You can have one global options block per Caddyfile.
{
# 'off' will disable HTTPS entirely (no cert management or redirects)
# 'disable_redirects' will disable only HTTP->HTTPS redirects
# 'disable_certs' will disable only certificate automation
# 'ignore_loaded_certs' will automate certificates even for names which appear on
# manually-loaded certs
auto_https off
