Please check first whether the service you have chosen works correctly. You may do this by watching the performance data shown in JonDo. For premium services, response times of 1000ms and below and speeds of 750 kbit/s and above are normal.

If the performance data of the service you have chosen are OK, then maybe a personal firewall or virus scanner, that is locally installed at your computer, impedes the JonDo connection.

For testing, deactivate both of these programs, and restart JonDo. If afterwards, the connections works correctly, please consult the manual and the support of your antivirus/firewall produces in order to fix the problem.

Some users report such problems in the context of the Internet Explorer. Partially, the connection does only work correctly after about 20 Minutes. The solution for that is easy: do not use the - slow and insecure - Internet Explorer, but JonDoFox.
