Discord RTC Connecting means your app cannot establish a live voice connection with the server. Fix it quickly by resetting your Discord voice settings, restarting your router, or flushing your DNS cache. Most RTC Connecting errors resolve within 2 minutes using one of the fixes below.
What Does RTC Connecting Mean on Discord
RTC stands for Real-Time Communication — the protocol Discord uses for voice channels. When Discord shows RTC Connecting it means the app is trying but failing to establish a voice connection with the assigned server.
RTC Connecting is a client-side error — it means something on your end or network is blocking Discord's voice connection. This is different from server-side errors like Awaiting Endpoint which occur when Discord's own servers are having issues.
Common causes:
- Your network is blocking Discord's UDP traffic
- A VPN or proxy is interfering with the voice connection
- Corrupted Discord voice settings
- Your DNS cache has stale entries blocking the connection
- A firewall or antivirus is blocking Discord
- The voice channel region is having issues
- Your IP address needs to be renewed
Fix 1 — Reset Discord Voice Settings
Corrupted voice settings are one of the most common causes of RTC Connecting. Resetting them takes 30 seconds:
- Open Discord and click the gear icon to open User Settings
- Click Voice & Video in the left sidebar
- Scroll all the way down
- Click Reset Voice Settings
- Confirm when prompted
- Rejoin the voice channel
Fix 2 — Restart Discord Completely
A full restart forces Discord to re-establish all connections from scratch:
- Right-click the Discord icon in your system tray
- Select Quit Discord — do not just close the window
- Open Task Manager (Ctrl+Shift+Esc) and check for any remaining Discord processes
- End any lingering Discord processes
- Reopen Discord and rejoin the voice channel
Simply closing the Discord window often leaves background processes running that maintain the broken connection.
Fix 3 — Flush DNS and Renew IP
Stale DNS cache entries can route your connection to outdated Discord servers causing RTC Connecting:
- Open Command Prompt as administrator
- Run these commands one by one:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
- Restart Discord and rejoin the voice channel
Flushing DNS clears cached entries. Releasing and renewing your IP assigns a fresh address that can reach Discord's voice servers directly.
Fix 4 — Disable VPN or Proxy
Discord's RTC voice protocol requires UDP — VPNs that block UDP or route traffic through incompatible servers cause RTC Connecting:
- Disconnect your VPN completely
- Disable any proxy settings in your system network settings
- Rejoin the Discord voice channel
If voice works without the VPN your VPN is causing the conflict. Switch to a different VPN server location or check that your VPN supports UDP protocol.
Windows proxy settings:
- Open Control Panel → Network and Internet → Internet Options
- Click Connections → LAN Settings
- Uncheck Use a proxy server for your LAN
- Click OK and restart Discord
Fix 5 — Change Voice Channel Region
If RTC Connecting only happens on one specific server the voice region may be having issues:
Requires Manage Channels permission or admin role:
- Right-click the voice channel
- Select Edit Channel
- Go to Region Override
- Change from Automatic to a specific region close to your location
- Save and rejoin
Try a few different regions if the first one does not work. You can also set it back to Automatic after the issue resolves.
Fix 6 — Check Firewall and Antivirus
Windows Firewall or antivirus software blocking Discord's UDP traffic causes RTC Connecting:
Windows Firewall:
- Open Windows Security → Firewall and Network Protection
- Click Allow an app through firewall
- Find Discord and ensure both Private and Public are checked
- Click OK and restart Discord
Antivirus: Temporarily disable your antivirus and test if Discord voice connects. If it does add Discord to the antivirus whitelist permanently.
Discord's voice protocol uses UDP on ports 50000-65535. Your firewall must allow outbound UDP traffic on these ports.
Fix 7 — Restart Your Router
A simple router restart resolves many RTC Connecting issues caused by stale network state:
- Turn off your router or modem
- Wait 30 seconds
- Turn it back on
- Wait 60-90 seconds for full reconnection
- Reopen Discord and rejoin the voice channel
Fix 8 — Change DNS Server
Your ISP's default DNS servers can sometimes block or slow Discord's voice server lookups:
Windows — Switch to Google DNS:
- Open Control Panel → Network and Internet → Network Connections
- Right-click your active connection → Properties
- Select Internet Protocol Version 4 → Properties
- Select Use the following DNS server addresses
- Enter:
- Preferred DNS:
8.8.8.8 - Alternate DNS:
8.8.4.4
- Preferred DNS:
- Click OK and restart Discord
Or use Cloudflare DNS: 1.1.1.1 and 1.0.0.1
Fix 9 — Use Discord Web Version
If the desktop app keeps showing RTC Connecting try the browser version as a temporary fix:
- Go to discord.com in Chrome or Edge
- Log in to your account
- Join the voice channel
If voice works in the browser the issue is specific to your Discord desktop app — try reinstalling the desktop app.
Fix 10 — Reinstall Discord
If all other fixes fail a clean reinstall resolves persistent RTC Connecting caused by corrupted installation files:
Windows:
- Uninstall Discord from Settings → Apps
- Press Win+R → type
%appdata%→ delete the discord folder - Press Win+R → type
%localappdata%→ delete the Discord folder - Download the latest Discord from discord.com
- Install and log back in
RTC Connecting vs Other Discord Voice Errors
| Error | Cause | Fix |
|---|---|---|
| RTC Connecting | Client-side network issue | Reset voice settings, flush DNS, disable VPN |
| Awaiting Endpoint | Server-side Discord issue | Check discordstatus.com and wait |
| No Route | Firewall blocking UDP | Allow Discord through firewall |
| ICE Checking | NAT or router issue | Restart router, change DNS |
Common Mistakes to Avoid
Just closing the app instead of fully quitting — Closing the Discord window leaves background processes running. Always quit from the system tray and check Task Manager.
Skipping the Reset Voice Settings fix — This resolves a large percentage of RTC Connecting errors in under 30 seconds and most users never try it.
Not testing without VPN — VPNs are one of the most common causes. Always disconnect your VPN first before trying more complex fixes.
Only flushing DNS without renewing IP — Flushing DNS alone sometimes is not enough. Run all three commands — flushdns, release, and renew — for the best result.
