How to Fix Discord No Route / RTC Connecting Error

The No Route or RTC Connecting error appears on Discord when you try to join a voice chat but the app cannot create a stable connection to the voice servers. This happens when Discord fails to build a complete network route between your device and the voice channel.

In simple terms, the error means Discord is not forming a valid UDP connection with the server.

• RTC Connecting: Discord is still attempting the voice handshake and setting up the voice channel.
• No Route: Discord could not reach the voice server and the connection process stopped.

Below are the methods that can help you fix this issue.

1. Use VPN

If your network blocks or restricts Discord’s route, the app cannot reach the voice servers. A VPN that supports UDP traffic creates a new connection path that bypasses the restriction and restores communication.

1. Download and install a VPN service that supports UDP traffic. You can use WARP.
2. Connect the VPN.
3. Restart Discord and rejoin the voice channel.

2. Change Voice Region (For Admins Only)

If the selected voice region does not match your network environment, Discord may struggle to create a clean route. Switching to a closer or more stable region sets up a better path for voice data.

1. Open the Voice Channel settings.
2. Go to Overview → Region Override.
3. Select a nearby region.
4. Save the settings and rejoin the channel.

3. Change WebRTC Mode to Non Proxied UDP (Opera Only)

Some Opera configurations interrupt Discord voice traffic because the browser’s proxy or VPN blocks UDP communication. Enabling Non Proxied UDP lets Discord send voice packets directly, avoiding the restricted route created by Opera.

1. Open Opera and go to Settings.
2. Search for WebRTC.
3. Select Disable non proxied UDP.
4. Close Opera and test Discord again.

4. Reset Voice and Video

Wrong or damaged voice settings can stop Discord from forming a valid route. Resetting restores the default audio system and removes misconfigurations that interrupt communication.

1. Open User Settings.
2. Open Voice and Video.
3. Choose the Debugging tab.
4. Click Reset Voice and Video Settings.
5. Confirm and allow Discord to reload the voice system.
6. Try joining a voice channel again.

5. Flush DNS

If your DNS cache holds outdated entries, Discord may be directed to the wrong server route. Flushing the DNS forces your system to request fresh and valid server addresses.

1. Search for Command Prompt and run it as Administrator.
2. Enter the commands:

   ipconfig /release

   ipconfig /flushdns

   ipconfig /renew

   

3. Restart your computer.

6. Disable IPv6

Some networks do not handle IPv6 correctly, which interrupts how Discord sends voice packets. Turning off IPv6 forces your device to use the more stable IPv4 routes.

1. Press Windows + R, type ncpa.cpl, and press Enter.
2. Right click your active connection and choose Properties.
3. Uncheck Internet Protocol Version 6 (TCP IPv6).
4. Click OK and restart.

7. Allow Discord Through Firewall

If Windows Firewall blocks Discord’s UDP traffic, the app cannot reach the voice server. Allowing Discord ensures voice data can move freely.

1. Search for Allow an app through Windows Firewall and open it.
2. Select Change Settings then Add another app. Choose Browse.
3. Find Discord or select Update.exe from its installation folder.
4. Enable both Private and Public options.
5. Restart your router and PC.

8. Use Discord Canary

If your current Discord build has a glitch, the Canary version may work better because it uses newer fixes that improve how voice routing works.

1. Download Discord Canary from Discord’s website.
2. Install it without removing your main Discord client.
