Set Up Connection Failed with MYSQL Database

Greeting to the great Team,
I am very new to Metabase.

I tried to Setup at Digital Ocean where I have another application(ERPNext).I have followed this instruction https://www.techrepublic.com/article/how-to-install-the-open-source-data-visualization-server-metabase/.

At the point of connection to the the MYSQL, the following error shows:"Database name : No matching clause: Could not connect to address=(host=localhost)(port=3306)(type=master) : Access denied for user 'root'@'localhost' (using password: YES) Current charset is UTF-8. If password has been set using other charset, consider using option 'passwordCharacterEncoding' "

This my diagnostic info:

    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36",

}

Any help will be deeply appreciated

Hi @Fredoluka

Are you sure you have allowed access to MySQL for root via localhost with that password?

That's a very outdated version of Metabase. Latest release is 0.38.2: https://github.com/metabase/metabase/releases/latest

And it seems like you might have skipped some steps, since it's using H2 as the application database instead of MySQL:
