why laravel Can't open connection to http://localhost:7474/db/data/?

Question

I have installed neo4j as root, it runs properly and accessible for all from everywhere except for my laravel application. it gives my the error "Can't open connection to http://localhost:7474/db/data/".

Then I removed it and reinstalled it with regular user but sudoer with sudo, and again can't be accessed but the status is running.

I can not install it without sudo.

My machine is CentOS VPS on Digital Ocean. I have set up the configurations Authentication variable of neo4j to false.

If someone can help would be appreciated.
