Discord RTC Connecting Fix Generator: Free Steps and Best Commands for 7 Errors

The Discord RTC Connecting fix generator gives you the steps and the Command Prompt lines for the Discord problem you have, whether voice is stuck on RTC Connecting or the app is caught in an update failed loop.

Discord problems split into two groups. Voice errors such as RTC Connecting, No Route and ICE Checking are network problems: something between you and the voice server is blocking UDP. Update and install errors are local: a damaged cache or a copy of Discord still running. The fixes do not overlap, so pick the one you see.

How the Discord RTC Connecting Fix Generator Works

Each problem in the Discord RTC Connecting fix generator has a cause, ordered steps and a set of commands. Voice problems get network resets. Update and install problems get the lines that close Discord and delete its two cache folders. Tell the tool if you use a VPN and it moves that check to the top, because a VPN without UDP support is the most common cause.

1. Pick the problem you see.
2. Pick your device.
3. Tick the VPN box if you use one.
4. Follow the steps in order.
5. On Windows, copy the commands into Command Prompt as administrator.

Discord Errors and What They Mean

Problem	What it means	First thing to try
RTC Connecting	Discord cannot open the voice connection. A firewall, VPN or router is blocking UDP.	Restart the router, the PC and Discord.
No Route	The voice server cannot be reached from your network.	Restart the router. A new IP address often clears it.
Awaiting Endpoint	Discord has not assigned a voice server yet. Usually an outage on Discord’s side.	Check the Discord status page.
ICE Checking	Discord is testing connection routes and none is working.	Turn off any VPN.
Update failed loop	The updater cannot download or replace its files, so it retries forever.	Close Discord from the system tray.
Installation has failed	The installer could not write its files, usually because an old copy is still running.	End every Discord process in Task Manager.
Stuck on a grey or blank screen	The app loaded with a damaged cache.	Press Ctrl+R to reload Discord.

Commands for RTC Connecting and No Route

Command	What it does
ipconfig /flushdns	Clears saved DNS lookups
netsh winsock reset	Resets the Windows network catalog
netsh int ip reset	Resets TCP/IP settings
ipconfig /release and ipconfig /renew	Gets a fresh local address from the router

Restart the PC after running them. If voice still sticks on RTC Connecting, switch Quality of Service High Packet Priority off in Voice and Video settings. Some routers drop packets marked that way.

Commands for the Discord Update Failed Loop

Command	What it does
taskkill /f /im discord.exe	Closes every Discord process
rmdir /s /q “%appdata%\discord”	Deletes the settings and cache folder
rmdir /s /q “%localappdata%\Discord”	Deletes the program and updater folder

After the folders are gone, download a fresh installer and run it as administrator. You will sign in again, but servers, friends and messages are stored on Discord’s side. The same reset fixes “installation has failed” and a grey screen at start-up.

Awaiting Endpoint and ICE Checking

Awaiting Endpoint means Discord has not handed your client a voice server. It is nearly always an outage or an overloaded region, so check the Discord status page and switch the channel region. ICE Checking means your client is testing routes and failing: treat it like RTC Connecting and start with the VPN and the router.

Discord RTC Connecting Fix Generator Worked Example

Voice sits on RTC Connecting and you use a VPN. Tick the VPN box in the Discord RTC Connecting fix generator and it lists eight steps with the VPN check first, plus four network commands. Switch the problem to the update failed loop and it gives six steps and four commands that close Discord, delete both folders and flush DNS.

About Discord

Discord is a chat app for text, voice and video, built around servers and channels. Voice runs over a real-time connection, shown in the app as RTC, that needs UDP traffic to reach Discord's voice servers.

The Windows app updates itself each time it starts, through an updater that lives in the local app data folder. When that updater breaks, the app loops.

The Discord RTC Connecting fix generator on this page is free to use, and we update it when the game changes its numbers.
