Your         


        

Answer 1

I have updated from 5.5 to 5.6

composer.json

"minimum-stability":"dev",
"prefer-stable": true,

This will install latest Laravel packages, then there will be issue with TrustedProxies.

Install the latest proxy version for Laravel 5.6.

Please use tag 4.0+ for Laravel 5.6:

composer require fideloper/proxy:~4.0
