Cannot Connect to FTP Client

SYSTEM INFORMATION
OS type and version macOS 11.6
Virtualmin version 6.17

Hi all! I’m working on setting up a VPS and am having some issues with getting this server up and running. While, according to both my Hostinger and Virtualmin accounts, the server is running with users attached to it, I cannot connect to the server via an FTP client (FileZilla) to begin migrating websites.

The error messages vary from “ECONNREFUSED - Connection refused by server” and “EAI_NONAME - Neither nodename nor servname provided, or not known” depending or whether I try to access it with the server name or IP address. I’ve checked the firewall setting on my computer as well as changing the port from 22 and 21.

Anyone have any thoughts regarding this? Am I missing something completely obvious? Thank you!
