An FTP connection tester lets you verify that a remote FTP server is online and accepting connections on the correct port. By entering a hostname, port, username, and password you can quickly confirm whether your credentials are valid, whether the server is reachable from outside your network, and whether any firewall or NAT rules are blocking the connection.
Common FTP connection issues
- Connection refused — the server is not listening on the specified port, or a firewall is blocking it.
- Authentication failed — incorrect username or password, or the account is locked.
- Timeout — the host is unreachable or the port is silently filtered by a firewall.
- Passive mode issues — the data port range is not open on the server-side firewall.
