Can't connect to MySQL database if I use IP instead of "localhost" in the connection URL

[Hol Demgun]

I utilize the `com.mysql.cj.jdbc.Driver` connector. Initially, I encountered difficulties in establishing a connection to `jdbc:mysql://localhost:3306/my_db` until I appended `bind-address="127.0.0.1"` to the MySQL configuration file, my.ini.

I got this error message:
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.


Now, moving on to a question that might sound a bit basic:
My computer is connected to the internet via a WiFi router that serves multiple devices. Is it feasible for a MySQL Server, reachable from the internet, to be hosted through this WiFi router? Could this potentially be the root of the issue?

I unsuccessfully tried to change bind-address in my.ini to the IP.
