This error, shown in the SurfBouncer log, is usually an indication of no connectivity to the internet. Before going further, first ensure that you are connected and can access web sites without SurfBouncer enabled.
In some cases your ISP or network operator may be blocking the UDP protocol that the default connections use to connect with. Please try using the TCP version of the connections shown in your connection menu and see if that resolves the issue.
Email us if these steps don’t resolve the issue and be sure to include a log showing the error.
