Starting with MySQL Workbench, unable to login to server (no replies)

Greetings, I am a new learner within SQL programming, and I am stuck on the following problem:

{

Your connection attempt failed for user 'root' to the MySQL server at localhost:3306:

The user specified as a definer

('mysql.infoschema'@'localhost') does not exist

}

This pops up, every time I try to connect to the given server within MySQL Workbench

Any detailed step by step help regarding this problem? and why it send me the error message? How to fix it?

Thanks!
