1. The problem I’m having:
I have a server using an EC2 with Amazon Linux 2. It runs behind an auto-scaling group, with a load balancer, and is a subdomain.
I performed the settings but got 308 e in the browser (to_many_redirects).
2. Error messages and/or full log output:

4. How I installed and ran Caddy
https://caddyserver.com/docs/running
a. System environment:
Amazon Linux 2
b. Command:
systemctl start caddy
systemctl reload caddy (for new inserts in CaddyFile)
d. My complete Caddy config:
debug{
www.multitenancy.abracadabra.com.br {
# Set this path to your site’s directory.
#tls /etc/caddy/cert.pem /etc/caddy/key.pem
#order foward_proxy before file_server
#reverse_proxy 127.0.0.1:9000
log
#root * /var/www/multitenancy.abracadraba.com.br/public
#php_fastcgi 127.0.0.1:9000
encode gzip
#php_fastcgi unix//run/php-fpm/php-fpm.sock
# Enable the static file server.
file_server
root * /var/www/multitenancy.abracadraba.com.br/public
# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080
# Or serve a PHP site through php-fpm:
php_fastcgi localhost:9000
}
