How to Fix Discord Stuck on 'RTC Connecting' or 'No Route'
Change the Discord Voice Region in Server Settings, disable Quality of Service (QoS) High Packet Priority in Discord Voice Settings, and flush your DNS.
Preliminary Fast Checks
Verify these 3 simple prerequisites before proceeding to in-depth fixes:
đŦ Root Cause: Why Does Discord RTC Connecting Occur?
Discord RTC (Real-Time Communication) Connecting or 'No Route' errors occur when WebRTC voice packets (UDP) cannot establish a peer-to-gateway handshake with Discord's regional voice server. This stems from router QoS packet shaping, VPN packet encapsulation, or restrictive firewall UDP port blocking.
đ Primary Triggers for Discord RTC Connecting
- Network firewall blocking Discord's WebRTC UDP audio streaming ports.
- Quality of Service (QoS) packet tagging conflicting with domestic Wi-Fi routers.
- Outdated or unresponsive Discord voice server region.
- Active VPN or third-party proxy intercepting voice data.
What NOT to Do
Avoid disabling your router firewall entirely; simply configure router UPnP or enable standard Discord voice ports.
Complete Step-by-Step Solutions for Discord RTC Connecting
Execute these verified methods sequentially from easiest to most advanced:
Disable Quality of Service (QoS) in Discord
Discord's QoS feature sends high-priority voice packets that many home and school routers reject.
In Discord, click the gear icon (User Settings) > Voice & Video > scroll down to 'Enable Quality of Service High Packet Priority' and toggle it OFF.
Change Server Voice Region
If you have server admin permissions, switching the voice channel region immediately resolves routing issues.
Right-click the voice channel > Edit Channel > Overview > Channel Voice Region > switch from 'Automatic' to a nearby specific country/region (e.g., US East, Central).
Flush DNS and Reset Winsock
Clear corrupted WebRTC routing tables from Windows.
netsh winsock reset
Open Command Prompt as Administrator, run the command above, then run 'ipconfig /flushdns', and restart your PC.
đĄ How to Prevent Discord RTC Connecting In the Future
- Use Discord's Automatic Voice Server Region setting for optimal ping.
- Keep network adapter drivers up-to-date in Windows Device Manager.
Frequently Asked Questions
School network firewalls deliberately block UDP voice streaming ports to prevent gaming and chatting during class hours.
Yes! Opening discord.com in Chrome or Firefox often bypasses network blocks because web traffic travels over standard HTTPS ports.
It means your computer cannot establish a direct UDP connection to the specific Discord voice server host.
