How to Fix Laravel HTTPS Redirect Loop on Amazon Elastic Beanstalk/Load Balancer/Proxy
If you are forcing HTTPS on routes in Laravel but are having issues with a redirect loop and your app is behind a proxy, load balancer, or something like Elastic Beanstalk, try adding this to your .htaccess file:
#Fixes HTTPS Redirect Loop SetEnvIfNoCase X-FORWARDED-PROTO "^https$" HTTPS
Many load balancers will accept HTTPS traffic and forward it internally as HTTP but pass an environment variable stating that the traffic received at the load balancer/proxy was intended for HTTPs. What this line does is checks for that environment variable
X-FORWARDED-PROTO and if it is set to
HTTPS remaps the request to HTTPS behind the proxy or load balancer.
