Cannot connect to MySQL on another PC

I want to access MySQL on my server PC at home from another PC at home, but I can't.
MySQL version is 8.0.

From another PC in the same IP address as the server PC

 mysql-u admin-p
ERROR 1045 (28000): Access denied for user 'admin' @ 'localhost' (using password: YES)

I can't connect as

 mysql-h 'IP address'-u admin-p 
ERROR 2003 (HY000): Can't connect to MySQL server on 'IP address' (10061)

and the IP address of your home cannot be connected.

The following requirements are met:

• The bind-address is not configured.
• The firewall is open 3306.
• MySQL port is set to 3306.
• admin is configured to be accessible from all IP addresses.

What should I do?
