The interruptions during your live are mainly due to a poor internet connection. To try to fix this, you’ll have to reduce the quality of your stream under Settings > Stream in your Radio Manager.
If you have a good connection, it is best to try with another software to check if it behaves in the same way.
If the same problem occurs with different software, it may be your firewall or antivirus that is the cause of all this, in which case you will have to go to your antivirus settings & allow live.radioking.com on port 80 in outgoing connection.
