Heads up

In case you are using the subfolder option, don't forget to configure the baseUrl option for autobrr:

config.toml

# Base url
# Set custom baseUrl eg /autobrr/ to serve in subdirectory.
# Not needed for subdomain, or by accessing with the :port directly.
#
# Optional
#
baseUrl = "/autobrr/"

Caddyfile

# Defaults
{
    admin off
    email YOUREMAIL@YOURDOMAIN.COM
    key_type p256
