I have seen the error come up multiple times with very few listed solutions online. I’ve tried a few and wanted to share it here at least. If you folks know more methods, please make sure to list them! These may not all solve your problems but I hope at least one of them will help.

FIXES FOR Error 0x21002001

——————————

1. Firewall — Allow Red Dead Redemption 2

Make sure to go to your Advanced Firewall settings in Windows and set up an Exception Rule for Red Dead Redemption 2 (rdr2.exe) to run.

This is one of the earlier concerns that people had and seems like the first thing you should check for.

2. Port Forwarding

Go to your router and set up port forwarding from your router. Here’s the link for more information on how to open up for the PC. The website is helpful with almost every single router available.

These are the ports to open.

3. Deleting Local Profile

This seems to have helped some people.From the Rockstar Launcher Go to Settings > Account Information > Delete Local Profileand sign back into the Launcher afterwards.

4. Using Hardwired Connection

If you’re having trouble with the Wifi, this seems to solve the most of the problems with people. Didn’t help me personally since I was already hardwired but an Ethernet Cable may be the solution to your problems.

5. Use VPN to play Red Dead Online

This was the solution that fixed my problem weirdly; by connecting to the VPN I was able to play RDO non stop for hours without any Error Codes, including 0x21002001. See if this helps with your issues as well.

——————————

Possible Causes?

This seems to stem from just poor connection overall and not necessarily related to your internet speed whatsoever.

1- Wifi Connection: Quite a few People reported this issue due to poor wifi signal

2- Double Router/Bridged Connections: In locations where a double router is used, this issue seems to be prevalent even if you’re hardwired.

3- Poor ISP Connection: If your ISP is crap, this issue tends to come up as well.

4- Outdated Game Build: Make sure the game is updated so most of the files are up-to-date.

Red Dead Online PC is facing errors and issues like Game Exited Unexpectedly, crash at launch, Error 0x21002001, random crashes, low audio, stuttering, and more. Here I have compiled a list of errors and issues that PC players are experiencing with RDR Online along with their fixes and workarounds.

Red Dead Online Crash, Stuttering, And Fixes

Rockstar Games has launched Red Dead Online as a standalone game. Meaning, players can enjoy the multiplayer-only mode for the game without having to download the full Red Dead Redemption. However, PC players are reporting errors and issues with Red Dead Online like Game Exited Unexpectedly, crash at launch, Error 0x21002001, low audio, and more.

The following are the errors and issues that PC players are experiencing with RDR Online along with their fixes and workarounds.

Game Exited Unexpectedly, Crash Fix

According to PC players, Red Dead Online crashes randomly while playing. For some, the game just crashes to the desktop while some are reporting “Game Exited Unexpectedly” error pops up when RDR2 crashes. Here is how to fix the Red Dead Online in-game crash issue.

Using third-party tools and software like MSI Afterburner or RGB software can cause the game to crash. Disable any third-party tools or software you are using along with Steam overlay and GeForce Experience overlay.

If you are playing RDR2 on a 4 Core/4 Thread CPU, then the CPU might be causing the game to crash. Red Dead Redemption 2 needs at least a 6 Core CPU to run properly. There might be a workaround for that. Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Red Dead Redemption 2. Set Low Latency Mode to “Ultra” and hit apply. This will stop the game from crashing.

In case the game is still crashing, your GPU might be the reason behind it. Either the GPU is overclocked or is old. If the GPU is overclocked, then revert it back to is default GPU clock even if it’s factory overclocked. If your GPU is old, then use MSI Afterburner to reduce the GPU clock by 100 Mhz. In case, you don’t want to mess with the GPU clock, then lock the game’s Max FPS. Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Red Dead Redemption 2. Turn on Max FPS Limit and set the value to 30. This will lock the game to 30 FPS and will reduce CPU and GPU load. Now the game won’t crash anymore while playing.

Error 0x21002001 Fix

A lot of Red Dead Online PC players are reporting that they are getting the Error 0x21002001. Here is how to fix Error 0x21002001 in RDR2.

One reason for the Error 0x21002001 could be the firewall blocking the game. Make sure to set up an Exception Rule for Red Dead Online in your Firewall. This will fix the error.

In case the Error 0x21002001 is still occurring then port forwarding is your next step. Check this link to see how to port forward. The following are the ports you need to open.

TCP 30211-30217
UDP 6672,61455-61458

Open the ports and the Error 0x21002001 will be fixed for Red Dead Online.

If the above fixes have failed to fix the error, then delete your local profile. Go to Settings > Account Information > Delete Local Profile and log in again to fix the error. Other fixes for Error 0x21002001 include using a wired connection or using a VPN.

Low Audio Fix

Players are reporting that they are getting low audio in Red Dead Online while the audio is working fine in other games and applications. This is due to the Windows volume mixer. For some reason, the volume mixer sets the audio level for RDR2 very low. Start the game and open the Volume mixer to raise the volume. This will fix the low audio issue with the game.

Game Not Starting, Crash At Sartup Fix

According to PC players, Red Dead Online is crashing at startup or not launching at all. Here is how to fix the RDR2 crash at launch issue.

One reason for the game to not launch could be the lack of admin rights. Right-click the game’s exe > Properties > Compatibility tab > check “Run this program as administrator” and hit apply. Launch RDR Online and it won’t crash at startup.

Your anti-virus/Windows Security might be blocking important game files and causing Red Dead Online to crash. Either disable the real-time protection or exclude the RDR Online’s install folder from it. After that, verify game files and the issue will be fixed.

In case the game is still crashing, right-click RDR Online in Steam library > Properties > Local Files tab > click Browse Local Files. Launch the game directly from the exe. The game should launch without any issue. However, chances are you’ll get an error similar to “vcruntime140_1.dll or MSVCP140.dll Was Not Found”. This can be fixed by installing the latest Microsoft Visual C++ Redistributables both x64 and x86 versions. Launch Red Dead Online and it won’t crash at startup.

How To Boost Performance, Stuttering Fix

Performance is a common issue in PC video games and RDR Online is specifically a demanding game. Players are reporting low FPS and stuttering while playing RDR Online and here is how to fix it.

First, make sure you have installed the latest GPU drivers and do a clean installation. Open Task Manager to see if there is any process using too much CPU, GPU, or HDD.

Launch the game and disable in-game v.sync and close the game. Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select Red Dead Redemption 2 and make the following changes and hit apply. These settings will potentially boost the game’s FPS will fix stuttering.

CUDA GPUs – “All”
Low Latency Mode – Ultra.
Set Power Management to “Prefer Maximum Performance”
Shader Cache – “On” only if you are using an HDD. Don’t need to enable it for an SSD.
Set Texture filtering – Quality to “High Performance”
Triple Buffering – “Off”
Set Vertical Sync to “On”
