Error: TCP: connect to address failed, will try again in 5 seconds

OpenVPN may display the error message "TCP: connect to address:port failed, will try again in 5 seconds: Operation timed out" in the OpenVPN log if is unable to connect to the remote VPN server.

Viscosity performs a "reachability check" before attempting to connect a VPN connection. This check allows Viscosity to determine whether the remote VPN server can theoretically be reached over the network so a connection can be established. As this check is passing it means the fault is unlikely to lie with your computer. It is more likely one of the following is the case:

  • The remote VPN server is down or unavailable. You will need to get in touch with your VPN Provider to check on the VPN server's status. If you are unsure of who your VPN Provider is please see How Do I Find Out Who My VPN Provider Is?.
  • You are being blocked from contacting the remote VPN server. This is not uncommon in countries that attempt to censor the Internet, or in some workplaces for security reasons. It is recommended you get in contact with your VPN Provider in this instance as well.
  • Your connection's configuration details may be incorrect or out of date. If you have set up the connection yourself, you should edit your connection in Viscosity and check that the Remote Server Address, Port, and Protocol options are correctly set. Some VPN Providers may periodically update their VPN servers, so you may need to download updated connections to import. Again, you will need to get in contact with your VPN Provider to ensure your configuration details are correct and up to date.
