Why does mysql.data.mysqlclient.mysqlexception 0x80004005 table 'xxx.xxx' doesn't exist error occur?

Question

MySQL

Good evening everyone!
Dear experts, tell me why this error occurs:

mysql.data.mysqlclient.mysqlexception 0x80004005 table 'xxx.xxx' doesn't exist

?
While writing, the base was on the local server. And now it's time for testing, I switched to a working server and I get this error :(
There is a connection to the server, the user and password are correct. SQLyog connects to the database under this account.
Advise something, I have already re-read everything and tried everything ... probably...
PS Application on C# WPF.

Answer 1

you connected to the server, and the schema with the same name and the table in it with the same name exist? does your user have rights to work with them?

use <schemaname>;
show tables like '<tablename>';
