Dears,

Note: This is not development task. As code is running already on local and it is not working on VPS.

I want to install multi tenancy on Laravel APP as backend. So, all customers will have different databases and one url for all customers as front
end. I am able to do on my local. But, it does not work on Hostinger VPS. I used to get following error once calling API.

1044 Access denied for user 'demolms'@'%

Mandatory Skills:
1. Laravel Multi tenancy
2. Hostinger VPS
