Access denied for user 'x'@'ip' (using password: YES)

Access denied for user 'x'@'ip' (using password: YES)

Hello,

This is maybe a strange question, but I am evaluating the mysql connector and I started by trying to generate a model Entity Developer (with entity framework - database first approach).

The problem is that I am not even able to connect to my server, which is a mysql 5.7 in a Google cloud enviroment.

I constantly get Access denied for user 'x'@'ip' (using password: YES) even when I know for sure that the password is correct. I can also see the log entry in my server.

I have a backup offline server with the same configuration that I can connect to with no errors.

Is there any known limitation to connect to Google Cloud MySQL 5.7? 

I really wish that I could replace my current entity framework native oracle implementation that is almost not officially maintained and has become a nightmare to upgrade, but at this point I cannot even start to evaluate the product.

Thanks in advance.
