ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061) (no replies)

I hope someone can tell me how to resolve the above error.

After I have added

[mysqld]
default-time-zone = 'UTC'

in my.ini file in MYSQL 8.0 workbench, I am losing the connection on localhost.

I am running MYSQL version 8.0.12 on windows 10.
