# For renewal to work, matrix-nginx-proxy (or another webserver, if matrix-nginx-proxy is disabled)
# need to forward requests for `/.well-known/acme-challenge` to the certbot container.
#
# This can happen inside the container network by proxying to `http://matrix-certbot:8080`
# or outside (on the host) by proxying to `http://127.0.0.1:{{ matrix_ssl_lets_encrypt_certbot_standalone_http_port }}`.
