Discord RTC Connecting Issue and How to Resolve It?

Posted by thetechtowns.com 21 January 2025

If you’ve ever used Discord for communication via voice You may have experienced the troublesome “RTC Connecting” issue. This issue prevents users from connecting to the voice channel, causing smooth communication between your team members or your friends. Although “RTC Connecting” may seem to be a technical issue that isn’t so obvious but it’s actually a typical issue with Discord’s communication and voice infrastructure.

This guide will go over the root causes behind Discord’s RTC Connecting problem, provide the technical basis behind it and offer practical solutions for you to fix the problem. No matter if you’re a player or remote worker, or just a casual users, this guide can assist you in restoring the Discord voice channels quickly.

What is RTC, and Why Does It Matter in Discord?

Prior to tackling the issue, we need to be aware of the basics of what RTC is, and how Discord depends on it.

RTC is a shorthand for real-time communication It is method for transmitting audio and video information in real-time via the internet. Discord utilizes WebRTC (Web Real Time Communication) the open-source framework that allows for seamless video and voice communication through your browser or mobile app. Discord’s WebRTC system guarantees:

  • Communication with voice that is low latency allows uninterrupted conversations
  • It is not necessary to add software or plug-ins to connect users.
  • Quality audio transmission, even in the most challenging network circumstances

But, RTC relies heavily on an internet connection that is stable functioning servers and the correct configuration. If one or more of these components fail, you could get the annoying “RTC Connecting” message.

Common Causes of the RTC Connecting Issue on Discord

There are a variety of factors that can cause the issue. The following are the most common causes listed for ease of understanding:

1. Network Connectivity Issues

  • unstable internet connectionIf your connection to the internet is sporadic or weak, Discord may struggle to get a reliable RTC connection.
  • Blocks UDP portsDiscord utilizes User Datagram Protocol (UDP) for voice communications. If the necessary ports are blocked by your firewall, or the network, RTC cannot establish communication.
  • VPN as well as proxy Interference: The use of an Virtual Private Network (VPN) or proxy server with no WebRTC support may create RTC problems.

2. Server-Related Problems

  • Discord Server Downtime Sometimes Discord’s voice servers can be down, which can prevent the user from connecting to the voice channels.
  • Incorrect server regionIncorrect Server Region: If the location of the server for a voice channel is distant from the physical place of residence, this could cause delays in the connection.

3. Local Device Configurations

  • Older Discord ApplicationDiscord running an older version of Discord could cause glitches and issues with connectivity.
  • firewall or antivirus LimitationsA zealous security settings for firewalls or antiviruses could stop Discord from accessing the needed ports.
  • Corrupted cache filesA corrupted application cache or data files could interfere with Discord’s ability for connection.

4. ISP or Router-Level Restrictions

  • ISP Restrictions on NetworksCertain Internet Service Providers can restrict or even stop UDP packets that are required to support RTC.
  • NAT (Network Address Translation) ProblemsIn the event that your router is set to the strictest rules for NAT, it can stop communication between Discord servers.

Steps to Fix the RTC Connecting Issue in Discord

This is a complete troubleshooting manual for resolving the RTC Connecting problem step by the step:

 1. Check Discord Server Status

  • To begin, go to the Status page of Discord to see if servers are down and causing problems. If you notice an outage it’s likely that the problem is at Discord’s part, and it will take a while until it is fixed.

2. Test Your Internet Connection

  • Check that your internet connection is stable, by conducting the speed test. If the connection appears to be to be unstable or slow, reboot the router/modem or dial your ISP for help.

3. Disable VPN or Proxy

  • If you’re making use of the VPN (or proxy), turn off it for a short period to determine if it can resolve the connectivity issue. You should use an VPN that is compatible with WebRTC when VPN utilization is essential.

4. Change Server Region in Discord

If the server’s current area is creating latency:

  • Check the server setting of the channel you’re trying join.
  • Go to Voice and Video, then Server Regionand move to a smaller area.
  • This is especially helpful when you have specific latency problems to their region.

5. Adjust Local Firewall/Antivirus Settings

Check that your firewall and antivirus software allows Discord to connect with you via UDP ports. Adjust settings:

  • Check your firewall’s settings, and look for any restrictions which are blocking Discord.
  • Incorporate Discord on the official list of applications that are allowed to be used.
  • If you are using antivirus you can temporarily turn them off and try reconnecting. If that resolves the problem then include Discord as an alternative.

6. Flush DNS and Reset Network Configuration

  • Problems with your network can also be solved by flushing DNS, or setting your network stack
  • If you are using Windows Open Command Prompt as an administrator and then type in:

“`

ipconfig /flushdns

netsh int ip reset

“`

  • Restart your computer, and then try connecting via the Voice Channel.

7. Clear Discord Cache

The corrupted cache file can cause disruption to Discord’s functions. For clearing the cache:

  • Stop the Discord application.
  • Navigate to `C:\Users\[YourUsername]\AppData\Roaming\Discord\Cache` and delete the files in this folder.
  • Reopen Discord and then try joining an audio channel.

8. Switch to a Different Network

  • If that doesn’t work If all else fails, connect to an alternative network (e.g. or wireless hotspot) to figure out what the issue is. the router or your ISP configuration.

Prevention Tips for Future RTC Issues

  • Software UpdatesBe sure to ensure that you have your Discord application is upgraded to the most current version.
  • Routing SettingsAllow an NAT configuration that is less restrictive If it is possible (e.g. setting the NAT setting to moderate or open).
  • regular maintenanceRegularly clear cache files for the application and then check for updates to the network or any changes that could hinder Discord’s ability to communicate.

When to Contact Support

If neither of the methods above works, call Discord Support for further assistance. Include the following details:

  • Operating system
  • Discord app version
  • Internet speed tests Results
  • Methods you’ve already tried

Final Thoughts

Discord RTC Connecting error Discord RTC Connecting error could cause frustration, however, the issue is usually fixed with regular problem-solving. Through addressing stability of the network the server’s settings, as well as local configurations, it is possible to fix the root of the problem. I hope this article has clarified RTC connectivity and equipped the necessary steps needed for resuming conversations without interruption.
