Website error when loading it the first time

i have the following problem when accessing my webiste

ProxySQL Error: Access denied for user ‘root’@‘2a02:4780:bad:f00d::f’ (using password: NO)

That means you have a script and it is wrongly configured.
Head to manage Database on 000webhost.com you’ll see your username and database name listed, you need to enter these into the configuration of your script alongside the password, if you can’t remember it you can change via Manage on manage database page too, and the host is always localhost not mysql.000webhost or anything.
