[google-cloud-sql-discuss] Access Denied from VB forums but able to connect from CLI

Hey everyone, I have an issue and I need some guidance.
I created a new Google Cloud MySQL instance and assigned trusted networks and users. I also created a new VM instance and gave it "Allow full access to all Cloud APIs"

When I log in the VM's terminal, I am able to run #mysql -h "Google Cloud Mysql IP" -u root -p without problems.However, 

when I configure a web application such as vbulletin with the same username and password. The MySQL instance gives an access denied error.

2018-01-30T15:33:13.950478Z 804 [Note] Access denied for user 'root'@'xx.xx.xx.xx' (using password: YES) 

 

What could be causing this issues?

Thanks for the help,

Sergio
