Problems with https in laravel

I have an VPS with vestacp installed. I have ssl certificate using letsencrypt. I have installed laravel and works fine when I try to load it via http. But when I try to load it via https I get a 403 error and a forbidden message. I have already tried some things like

How to implement HTTPS in laravel 5.4

And using middleware like this other thread.

Laravel 5 - redirect to HTTPS

But I'm still getting same error.
