This is said to happen when you try to connect to a server on a different continent. In this scenario, the response is an administrator’s request to change the server’s voice region.

VPN: Discord does not accept VPNs that do not use the User Datagram Protocol (UDP). Since Discord is designed to only work with VPN systems that support UDP, this is a common occurrence.

The network does not support QoS. Your network may not support high packet priority QoS. Luckily, Discord users can turn it off in their Voice & Video settings.

Discord is disabled by antivirus: Your antivirus program may flag the Discord file as dangerous. The antivirus immediately quarantines it, preventing your connection from working.

5. Disable QoS (Quality of Service) in Discord

Issues with Discord RTC have been reported multiple times. They were fixed by removing QoS in user settings. This issue occurs when computers cannot meet the requirements for the High Service Pack Priority service.

7. Turn off your antivirus program and Windows Firewall.

A third-party antivirus or Windows Defender Firewall is interfering with Discord. The firewall controls unauthorized access to files and resources on your computer. As a result, it can interfere with traffic related to Discord. This results in an RTC connection problem.

It’s also possible that your antivirus software has placed Discord files in a quarantine folder. This makes it impossible for the service to function normally.

To temporarily disable Windows Defender Firewall, follow these steps:

• To access the Run accessory, press the Windows + R key combination on your keyboard.
• Type or click OK after typing “control firewall.cpl”(without quotes).
• In the left pane, select Turn Windows Defender Firewall on or off.

Try joining a Discord chat. After that, re-enable Windows Defender Firewall or third-party antivirus. Then move on to the next step in the article.

8. Try another browser

You can’t join Discord chat because of your browser. Discord users may install certain incompatible plugins. Browser cache may be causing issues with the Discord site.

All you have to do now is delete your browsing history before disabling all extensions. After that, try reinstalling Discord. If the problem persists, try using a different browser. Check if you can start a chat without getting stuck on the RTC connection screen.

• If the issue is resolved after you have followed the steps above, you can continue to use your browser.

9. Check your VPN connection

When a user is actively using a VPN solution that is not configured to use UDP, an RTC connection error occurs. The Discord app is not compatible with VPNs that don’t use the User Datagram Protocol (UDP).

If you are using a VPN, check your service provider’s website to learn how to use UDP. You can also see if the VPN is causing the issue by disabling it and connecting to Discord using a different voice server.

Let’s say you find that your VPN provider is causing the problem. You can switch to a different VPN provider or disable the “anonymity service”when using Discord.

10. Change to the following DNS server addresses

DNS is a system that associates URLs with IP addresses. When you visit a website, you can enter words and phrases into the browser instead of a string of numbers.

DNS clients can access the origin server because your DNS server translates domain names into IP addresses. As a result, it is clear that this can affect the speed and accuracy of browsing.

Change your DNS server from the one provided by your ISP. Commonly used ones like Google DNS are the best choice.

• To launch the Run dialog, press the Windows Key + R. Then, to install the Control Panel, type “control”and press Enter.
• Go to “Network and Internet”> “Network and Sharing Center”in Control Panel. Then, to connect to a private network, click the Connections hyperlink.

  • Preferred DNS Server

8.8.8.8

• Alternate DNS Server

8.8.4.4

• Then click OK to save your changes.
• Restart your computer after closing all open windows.
• Your Discord app should connect to the new voice server with no RTC connection issues.
• If the problem persists, continue to the next procedure below.

11. Set a different server region in Discord

If you encounter this error only when calling a friend on the other side of the world. The problem is probably related to the fact that the server’s voice region is different from yours.

The answer, in this case, lies in the request. The administrator has set an alternate voice region in the server settings.

The administrator can change the server settings by following the steps below.

• Launch Discord and go to the Server tab.
• Go to the top left corner of the window and click on your server name.
• Then expand the dropdown menu and select Server Settings from the list.
• Select Edit from the dropdown menu. It can be found under the “Server Region”tab.
• Select the server region from the dropdown menu.
• Back up your changes and try connecting again.

12. Run an RTC connection test

If none of the previous solutions worked, you can try running the test on your PC. Here’s how to do it:

• Go to the WebRTC website to learn more.
• To start the test, click the green “Start”button at the top of the page.
• Wait until the end of the procedure. This will probably take 4 minutes to complete.
• When the results show up, see if you can correct any errors.

13. Remove Third Party Firewall or Discord Whitelist.

Another reason for the No Root issue could be overprotection of the antivirus. The firewall is preventing Discord from supporting outgoing connections.

Disabling real-time protection will not be permanent. To determine if your security solution is causing the problem. The same rules will remain in effect.

The only way to check if this scenario is applicable is to uninstall your antivirus software. Check if Discord was able to connect to the new voice server.

• To open the Run dialog, press the Windows key + R. Then, to open Programs and Features, type “appwiz.cpl”and press Enter.

• Scroll down to find the third-party security solution under Programs and Features. Then right-click on it and select Delete.
• Remove the third-party antivirus or firewall by following the on-screen instructions.
