Connecting to mysql on another server from docker?

Question

MySQL

I'm trying to connect to mysql on another server using a golang program. The program itself is in a docker container.

db, err := sql.Open("mysql",  "test:[email protected](11.11.11.11:3306)/test?charset=utf8")
if err != nil {
  return nil, err
}

returns an error

Error 1045: Access denied for user "test"

• Connects from a local computer from a container
  
• Connects from the combat server if the program is not run in a container
  
• On mysql server all connections are allowed
  
• Problems not only with one database, there are 4 databases on different servers
  

What could be the problem?

Answer 1

The host of the user is incorrect (of course, if the name and password are exactly correct and there are grants).
Mysql 1045 access denied for user
