Your computer freezes mid-game, and a Discord error pops up, but the real issue is a network handshake failure. If you are searching for how to fix a discord rtc connecting error, you are likely staring at a spinning circle instead of hearing your friends. This error usually means Discord cannot establish a stable connection for voice chats, often due to firewall blocks or DNS hiccups. Let us walk through the fixes step by step, so you can get back to talking without the lag.
Discord uses Real-Time Communication (RTC) to handle voice and video. When this fails, you see the “RTC Connecting” message. It is annoying, but usually fixable without reinstalling Windows. Below is a structured guide to resolve this issue.
How To Fix A Discord Rtc Connecting Error
Before diving into advanced fixes, try the simplest solution first: restart Discord and your PC. Many temporary glitches clear up with a reboot. If that does not work, move to the steps below.
Check Your Internet Connection
A weak or unstable internet connection is the most common cause. Run a speed test to ensure your ping is low and your connection is stable. If you are on Wi-Fi, try switching to a wired ethernet cable for better reliability.
- Restart your router and modem by unplugging them for 30 seconds.
- Close bandwidth-heavy apps like streaming services or large downloads.
- Use a VPN if your ISP throttles Discord traffic.
Disable Proxy Settings
Proxies can interfere with Discord’s RTC connection. Windows often has proxy settings enabled by default from previous configurations.
- Press Windows + I to open Settings.
- Go to Network & Internet > Proxy.
- Turn off “Use a proxy server” and “Automatically detect settings.”
- Restart Discord and test the connection.
Adjust Discord Voice Settings
Sometimes the issue is within Discord itself. Changing the voice server region can force a fresh connection.
- Open Discord and go to User Settings (gear icon).
- Click on Voice & Video.
- Under “Voice Settings,” find “Server Region” and select a different region close to you.
- Scroll down to “Quality of Service” and disable “Enable Quality of Service High Packet Priority.”
- Restart Discord.
Flush DNS Cache
A corrupted DNS cache can prevent Discord from resolving server addresses correctly. Flushing it is quick and safe.
- Open Command Prompt as Administrator (search “cmd,” right-click, run as admin).
- Type
ipconfig /flushdnsand press Enter. - Type
ipconfig /renewand press Enter. - Restart your computer.
Change DNS Servers
Your ISP’s default DNS might be slow or unreliable. Switching to Google DNS or Cloudflare DNS often fixes RTC errors.
- Open Control Panel > Network and Sharing Center.
- Click on your active network connection.
- Select Properties, then double-click “Internet Protocol Version 4 (TCP/IPv4).”
- Choose “Use the following DNS server addresses.”
- Set Preferred DNS to
8.8.8.8and Alternate to8.8.4.4(Google). Or use1.1.1.1and1.0.0.1(Cloudflare). - Click OK and restart Discord.
Allow Discord Through Firewall
Windows Defender or third-party antivirus software might block Discord’s RTC ports. You need to create an exception.
- Open Windows Security (search in Start menu).
- Click on Firewall & network protection.
- Select “Allow an app through firewall.”
- Click “Change settings,” then “Allow another app.”
- Browse to Discord’s installation folder (usually
C:\Users\YourName\AppData\Local\Discord) and addDiscord.exe. - Ensure both Private and Public boxes are checked.
- Restart Discord.
Disable IPv6
IPv6 can sometimes cause compatibility issues with Discord. Disabling it forces your system to use IPv4, which is more stable.
- Open Control Panel > Network and Sharing Center.
- Click on your network connection, then Properties.
- Uncheck “Internet Protocol Version 6 (TCP/IPv6).”
- Click OK and restart your PC.
Update Network Drivers
Outdated or corrupt network drivers can lead to connection problems. Updating them is a good preventive measure.
- Press Windows + X and select Device Manager.
- Expand “Network adapters.”
- Right-click your network card and choose “Update driver.”
- Select “Search automatically for drivers.”
- If no update is found, visit your motherboard or laptop manufacturer’s website for the latest driver.
Reset Winsock
Winsock is a programming interface that manages network connections. Resetting it can fix deep-level issues.
- Open Command Prompt as Administrator.
- Type
netsh winsock resetand press Enter. - Type
netsh int ip resetand press Enter. - Restart your computer.
Reinstall Discord
If all else fails, a clean reinstall can remove corrupted files that cause the RTC connecting error.
- Uninstall Discord from Control Panel or Settings.
- Delete leftover folders:
%appdata%\Discordand%localappdata%\Discord. - Download the latest version from the official Discord website.
- Install and log in.
Check Antivirus Software
Third-party antivirus programs like Norton or McAfee can block Discord’s ports. Temporarily disable them to test. If the error stops, add Discord to the antivirus whitelist.
Use Discord Web Version
As a temporary workaround, use Discord in your browser. Go to discord.com and log in. The web version uses different network protocols and may bypass the RTC error.
Adjust Quality Of Service Settings
Discord’s Quality of Service (QoS) feature can sometimes cause conflicts. Disabling it often resolves the RTC connecting issue.
- Go to User Settings > Voice & Video.
- Scroll to “Quality of Service.”
- Toggle off “Enable Quality of Service High Packet Priority.”
- Restart Discord.
Change Server Region In Voice Channel
If you are in a specific server, you can change the voice channel’s region manually.
- Join a voice channel in your server.
- Click the channel name and select “Edit Channel.”
- Go to “Overview” and find “Region Override.”
- Choose a different region, like US East or Europe West.
- Save changes.
Clear Discord Cache
Corrupted cache files can cause various errors, including RTC connecting. Clearing them is safe and easy.
- Close Discord completely (check system tray).
- Press Windows + R, type
%appdata%\discord, and press Enter. - Delete the “Cache,” “Code Cache,” and “GPUCache” folders.
- Restart Discord.
Use A VPN
Some ISPs throttle Discord traffic, causing RTC errors. A VPN encrypts your connection and can bypass throttling. Free VPNs like ProtonVPN or paid ones like NordVPN work well.
Disable Hardware Acceleration
Hardware acceleration in Discord can sometimes interfere with network handling. Disabling it might help.
- Go to User Settings > Advanced.
- Toggle off “Hardware Acceleration.”
- Restart Discord.
Check For Windows Updates
Outdated Windows versions can have network bugs. Install the latest updates to ensure compatibility.
- Press Windows + I, go to Update & Security.
- Click “Check for updates.”
- Install any pending updates and restart.
Run Network Troubleshooter
Windows has a built-in troubleshooter that can automatically detect and fix network issues.
- Go to Settings > Update & Security > Troubleshoot.
- Select “Additional troubleshooters.”
- Choose “Network Adapter” and run the troubleshooter.
- Follow the on-screen instructions.
Disable Third-Party Overlays
Overlays from apps like MSI Afterburner or Nvidia GeForce Experience can conflict with Discord’s RTC. Disable them temporarily to test.
Use A Different Voice Server
If you are in a large server, the voice server might be overloaded. Ask the server admin to change the voice region in server settings.
