What Causes the Discord No Route Error?
Through investigation and various user reports, we’ve identified several scenarios that might cause this error:
The IP address assigned to the PC has changed – Common with Dynamic IP addresses that change regularly. Restarting your Modem, Router, and Computer can often resolve this.3rd party Firewall or Antivirus is blacklisting Discord – When this happens, Discord is not allowed to maintain an outgoing connection with an external server.The computer is using a VPN without UDP support – Since Discord is designed to work only with VPN solutions that support UDP (User Datagram Protocol), other VPNs can cause connection problems.Network admin has blocked Discord – If you’re trying to use Discord at work or from a school network, it may be blocked.QoS doesn’t work with your network – Your network may not be optimized to support Quality of Service (QoS) High Packet Priority. Disabling this feature in the Voice & Video settings might help.
How to Fix the No Route Error
If you’re struggling with this particular Discord error, this article offers a collection of troubleshooting steps. Others users with similar problems have successfully followed these methods to resolve the issue. Begin with the first method and proceed in order until you find a solution that works for you. Before proceeding with the solutions, make sure that your network is set to private rather than public.
1. Restart Modem/Router And Computer
Restarting your modem/router and PC refreshes your network connection, potentially clearing IP configuration issues and renewing the lease of the IP address which might have changed, especially if your setup uses dynamic IP allocation. Additionally, it assists in resolving temporary glitches within the modem/router or the networking stack of your operating system that could be causing issues with Discord’s ability to establish a stable connection to its voice servers. After restarting, check if you can connect to Discord voice servers without encountering the error. If the error persists, proceed to the next method.
2. Uninstall 3rd Party Firewall or Whitelist Discord (If Applicable)
Firewalls scans data coming in and out of your network, enforcing security by blocking suspicious traffic. Sometimes, though, they might be a bit overprotective and mislabel Discord as a threat, leading to the error. By uninstalling the firewall or adding Discord to its whitelist—a list of approved applications—you signal to the firewall that Discord’s traffic is safe, thereby restoring its ability to connect to voice servers without issues.
3. Check Your VPN or Use a UDP-Compatible One (If Applicable)
The No Route error can also be related to VPN services that do not utilize the UDP protocol, which is required for Discord to function correctly. If you’re using a VPN that lacks UDP (User Datagram, a core component of internet traffic), Discord may struggle to communicate properly. By switching to a VPN that supports UDP, you enable the smooth data transfer Discord needs to connect to voice channels effectively.
4. Check if Discord is Blocked by Your Network Admin
In environments like schools or workplaces, IT personnel often implement filters to limit access to certain applications, including Discord, for security or productivity reasons. By making sure that Discord isn’t being blocked by these administrative controls, you can potentially overcome connectivity issues and regain access to your voice channels. If you find that Discord is indeed restricted on your network, you may need to have a discussion with your network admin to see if the restriction can be lifted for your use. You can also try a workaround to avoid this block, but be aware that you may face consequences.
5. Disable QoS From Voice & Video Settings
The Quality of Service (QoS) feature aims to prioritize voice packets to ensure stable voice quality. However, not all networks support these advanced features. By turning off QoS in the Voice & Video settings, we remove potential conflicts that might occur if your network equipment doesn’t handle these prioritized packets correctly.
8. Flushing the DNS Settings
When you clear out the old address records your device has stored, any incorrect or outdated info gets wiped clean. This means your system has to ask for new, accurate directions to find websites and servers—including Discord’s voice servers. By doing this simple cleanup, you might just smooth out any connection issues that were causing those errors.
8. Allow Discord Through Firewall
Sometimes, the firewall may mistakenly view Discord as a potential threat, automatically preventing it from establishing a connection to the internet. By manually allowing Discord through the firewall, you reassure the system that it’s a trusted application, thereby granting it permission to transmit voice and data without being blocked by your computer’s security measures. If the above solution doesn’t resolve the error, the problem might lie with your ISP’s routing. Contact your ISP to inquire whether there are any known issues with routing to Discord’s servers.
