SQLSTATE[HY000] [1045] Access denied for user 'lagaikha_cricketuser'@'lin1505.byte90.net' (using password: YES) Laravel 5.2 on Live Web Server

I am trying to login on my website which is built in laravel 5.2 but I am getting this error of access denied for user on my live web server. I have also put credentials in .env file that are shown below:

APP_URL=http://lagaikhaiexchange.com
    
    DB_CONNECTION=mysql
    DB_HOST=lagaikhaiexchange.com
    DB_PORT=3306
    DB_DATABASE=mydatabase
    DB_USERNAME=myuser  
    DB_PASSWORD=mypassword

and I also gave the all privileges to user lagaikha_cricketuser But I am unable to find that why my application is not connecting to database. Although On localhost, the same code working fine and doing everything. Any help would be appreciated... Thank you
