What "RTC Connecting" means and why it happens

When Discord shows "RTC Connecting" in the bottom left corner of your screen, it means the app is trying to establish a real-time communication connection for voice or video calls but cannot complete the handshake. RTC stands for Real-Time Communication — the protocol Discord uses to route your voice and video to other users. If this connection fails, you can see the message hang indefinitely, or calls may drop repeatedly.

The most common causes are network configuration issues on your device, firewall or antivirus software blocking Discord's connection ports, outdated Discord software, or problems with your internet connection itself. Less often, Discord's servers experience temporary outages that affect many users at once.

Key Takeaways

  • Restart Discord completely — close it from the system tray, not just the window, then reopen it to reset the RTC connection.
  • Check that your firewall or antivirus is not blocking Discord by temporarily disabling it or adding Discord to its exception list.
  • Update Discord to the latest version through the app's settings menu, as older versions sometimes fail to connect properly.
  • Switch your network connection — try a different Wi-Fi network, mobile hotspot, or wired ethernet to isolate whether the problem is your connection or your device.
  • Check Discord's status page at status.discord.com to confirm whether the outage is on Discord's side before troubleshooting your own setup.

Restart Discord completely, not just the window

The first step is a full restart of the Discord application. Many users close the Discord window but leave the app running in the background, which means the RTC connection never fully resets. On Windows, look for the Discord icon in the system tray (the small icons near your clock in the bottom right). Right-click it and select "Quit Discord". On Mac, click the Discord menu at the top and select "Quit Discord".

Wait 10 seconds, then reopen Discord. This forces the app to rebuild its connection to Discord's servers from scratch. If the RTC Connecting message clears within 30 seconds of opening, the problem was a stalled connection state and you are done.

Update Discord to the current version

Outdated Discord versions sometimes fail to negotiate the RTC connection properly. Open Discord and look for a settings icon (a gear) in the bottom left. Click "User Settings", then scroll down to "App Settings" and select "About". Discord will check for updates automatically. If an update is available, you will see a button to install it. Restart Discord after the update completes.

If you are on a work or school network, your organization may have disabled automatic updates. In that case, uninstall Discord completely and download the latest version from discord.com/download. This is slower but ensures you have the newest build.

Check your firewall and antivirus settings

Firewalls and antivirus software often block the ports Discord needs for voice and video. The most direct fix is to temporarily disable your antivirus or firewall to test whether it is the culprit. On Windows, open Settings, go to "Privacy & Security", select "Windows Defender Firewall", and click "Allow an app through firewall". Look for Discord in the list. If it is there but unchecked, check both the "Private" and "Public" boxes. If Discord is not in the list, click "Allow another app" and browse to your Discord installation folder to add it.

For third-party antivirus (Norton, McAfee, Kaspersky, etc.), the process varies, but most have a settings menu where you can add exceptions or whitelist applications. Search your antivirus name plus "add exception" or "whitelist" to find the exact steps. If you are unsure whether your antivirus is blocking Discord, disable it for 5 minutes, try a Discord call, and re-enable it. If the call works with the antivirus off, you have found the problem.

Switch your network connection to isolate the problem

Network configuration on your device or router can prevent RTC from connecting. The quickest way to test this is to switch to a different network entirely. If you are on Wi-Fi, try connecting to a mobile hotspot from your phone. If you are on a mobile hotspot, try Wi-Fi. If you are on ethernet, try Wi-Fi. If the RTC Connecting error disappears on the new network, the problem is your original network or router, not Discord or your device.

If you must use your original network, restart your router by unplugging it for 30 seconds and plugging it back in. This clears the router's memory and forces it to renegotiate connections. Some routers also have a setting called "UPnP" (Universal Plug and Play) that helps applications like Discord open ports automatically. Log into your router's admin panel (usually 192.168.1.1 or 192.168.0.1 in your browser) and enable UPnP if it is available.

Check Discord's server status before troubleshooting further

Before spending time on your own setup, confirm that Discord's servers are not experiencing an outage. Go to status.discord.com in your browser. If you see a red or yellow indicator next to "Voice Connections", Discord's infrastructure is having problems and there is nothing to fix on your end. Wait for the status page to show green before continuing.

If the status page shows all systems operational but you are still seeing RTC Connecting, the problem is specific to your device or network.

Clear Discord's cache and reinstall if nothing else works

Discord stores cached connection data that can become corrupted. On Windows, press Windows key + R, type %appdata%\Discord, and press Enter. Delete the entire Discord folder. On Mac, open Finder, press Command + Shift + G, type ~/Library/Application Support/Discord, and delete the Discord folder. Then uninstall Discord completely and download a fresh copy from discord.com/download.

This is a last resort because it removes all your local settings, but it clears out any corrupted cache files that might be preventing the RTC connection. After reinstalling, log back in and test a voice call.

Frequently Asked Questions

Does RTC Connecting mean I have been disconnected from the server?

No. RTC Connecting means Discord is trying to set up the voice or video connection specifically. You remain connected to the text channels and can still send messages. The RTC layer is separate from the main Discord connection.

Why does RTC Connecting happen only in certain servers?

Some servers are hosted on Discord's infrastructure in regions far from you, which can cause connection delays. Try switching to a different voice channel in the same server, or ask the server owner whether they have changed the server region in settings. You can also check your own region in User Settings > Voice & Video > Voice Server Region.

Will a VPN help fix RTC Connecting?

Sometimes. If your internet provider or network is blocking Discord's ports, a VPN can route around that block. However, VPNs can also slow your connection and make voice quality worse. Try it only if other steps have not worked, and disconnect the VPN if it does not help within a few minutes.

What if RTC Connecting clears but my voice is choppy or cuts out?

That is a different problem from RTC Connecting — it means the connection is established but your bandwidth or network stability is poor. Close other applications using the internet, move closer to your Wi-Fi router, or switch to a wired ethernet connection if possible.
