| If you find DHCPNACK errors in the Event Viewer, your DHCP server may be briefly denying your IP address, causing your existing connections to fail. Where possible, this can be addressed by reserving a specific IP address on the DHCP server (e.g. cable modem/router), setting that as the static IP address, and disabling the DHCP client service. | If you find DHCPNACK errors in the Event Viewer, your DHCP server may be briefly denying your IP address, causing your existing connections to fail.

| + | You may get this message when connecting to a server for following reasons: | ||
| + | * You may have typed a wrong hostname on Login dialog. | ||
| + | * Your domain name is new and is not fully distributed to DNS servers yet. | ||
| + | * Connection was blocked by firewall. Please refer to [[faq_connection_refused|FAQ]]. | ||
| + | * Problem with DNS server. | ||
| + | * Common mistake is to enter full URL (e.g. ''%%ftp://ftp.example.com%%'') as hostname on Login dialog instead of actual hostname (e.g. ''%%ftp.example.com%%''). | ||
| + | * In [[scripting]], you may get this error when using ''open site_name'' syntax in an environment, where stored site ''site_name'' does not exist. The ''site_name'' will then be used as a hostname instead. See [[faq_environment|Why does WinSCP not work in a new environment (operating system, machine, user account, network), when it works for me in a different environment already?]] | ||
| + | * Server IPv6 address might by misconfigured. Try forcing IPv4 in //[[ui_login_connection|Internet protocol version]]// session settings. | ||
