Caprover php fpm 502 issue

Question

I'm using CapRover in my VDS (virtual dedicated server) and I want to deploy my Laravel application. When I run the CapRover deploy command there is no problem with deployment. Also, the PHP Artisan migrate command is running, my tables created successfully, but when I go to the URL, CapRover return NGINX 502 Error.

here my Dockerfile:
