External Query to MySQL Cloud Database

[Noesis]

Hello 👋
I have gone throw the following tutorials:
https://cloud.google.com/bigquery/docs/cloud-sql-federated-queries
https://www.youtube.com/watch?v=0cyTHbkARwY&ab_channel=GoogleCloudTech

But every time I try to do an external query to my MySQL database on Google cloud, from Big Query, I receive the following error:
Invalid table-valued function EXTERNAL_QUERY Failed to connect to MySQL database. Error: MysqlErrorCode(1045): Access denied for user 'xxxxx'@'cloudsqlproxy~' (using password: YES) at [1:15]

Does anybody had a similar issue?
