Fluent Hiberante. How to avoid changing the username during MySql authentication?

Question

MySQL

Good day.
I am making an ASP.NET website, working with MySql database via FluemtHibernate. On the local machine, everything is OK, when I throw it on hosting, an authentication error occurs. Error: MySqlException (0x80004005): Authentication to host 'myHost' for user 'myUser' using method 'mysql_native_password' failed with message: Access denied for user 'myUser'@' csSitesShared11 ' (using password: YES) .
Host available.
The difference between the local version and the "hosting" version is that the MySql.Data, MySql.Web, MySql.Fabric.Plugin, MySql.Data.Entity.EF5 libraries are copied there locally.
In which direction can you dig?
