Can't connect to MySQL db

Hello,

I’ve got a droplet that run ubuntu and I’ve installed mysql to it. I can reach it from my computer with SSH connection from mysql workbench, so the remote access is ok. The hostname is : 127.0.0.1

The bind address in my mysqld.cnf: 127.0.0.1

I’ve got a .net core api and I would like to use docker to run it. I made the container push to docker hub and pulled it to the droplet. When i try to run I get this error: An error occurred using the connection to database ‘’ on server ‘127.0.0.1’.

My connection string: “Server=127.0.0.1;Port=3306;Database=db;Uid=user;Pwd=pass”

i tried to server:

• localhost
• the ip of my server

I don’t understand why can I connect to db from mysql workbench and cannot from .net core web api.

The .net core version is 3.1

Thank you for the answer
