While Discord was geared toward being a VoIP (Voice-over-IP) application for video game users initially, it has become one of the world's prominent social media platforms. Discord has amassed over 250 million users and gives them the ability to establish separate groups based on different interests and topics. As with any software application, errors are not that uncommon. One such possible issue is the appearance of the 'Discord No Route' error.
Users who are experiencing this particular problem should know that it may be several different reasons causing it. The error might appear if their computer's IP address has been changed, a common occurrence when the user has a Dynamic IP address. Anti-malware solutions also could interfere with the normal Discord operation by limiting or restricting outgoing connections. In that case, users either disable their anti-malware program of choice temporarily or add the Discord application to its Exceptions list.
In the last several years, VPNs' usage (Virtual Private Networks) has seen a drastic increase due to the security protections they provide. Using a VPN that doesn't support UDP (User Datagram Protocol) could cause the 'Discord No Route' error to start appearing. Try to disable the VPN and see if this fixes the issue.
Another possible cause for this particular error is if the Quality of Service High Packet Priority has been enabled in Discord. Still, the user's ISP (Internet Service Provider) doesn't support Quality of Service (QoS). To know if this is the case:
- Open the Discord program and then click on User Settings (the gear icon close to your profile name).
- Find Voice & Video from the list on the left and click on it.
- Scroll down until you encounter the Quality of Service section. If the Enable Quality of Service High Packet Priority option has been enabled, click on the button to disable it.
- Try to see if this has managed to fix the 'Discord No Route' error.
