Firewall

IP addresses or networks (203.0.113.5, 198.51.100.0/24), one per line or separated by commas. Your address now: 216.73.216.102

Connections are filtered by the country of their IP address. "Allow only from the selected sources" with countries needs ports (a custom rule), so that no other port is opened to them. Check that your own country is allowed before you apply a rule on SSH or the panel.
