Quick Summary
The 'Discord No Route' error indicates that your Discord client is unable to establish a reliable connection to the voice server. This usually means there's a problem with your network configuration, the Discord server, or a firewall blocking the connection.
Common Causes
- Network Connectivity Issues: General network problems could be preventing Discord from connecting. This includes issues with your internet service provider (ISP), router, or modem.
- Firewall Interference: Your firewall or antivirus software might be blocking Discord's connection to the voice server.
- Incorrect Voice Region: The voice region selected for the Discord server might be experiencing issues or not be optimal for your location.
- Quality of Service High Packet Priority (QoS): This setting, intended to prioritize Discord traffic, can sometimes interfere with the connection and cause problems.
- Discord Server Issues: Occasionally, Discord's servers may experience downtime or technical difficulties, leading to connection problems.
