How To Fix Anydesk Not Working In Windows 11

AnyDesk is a lifeline for millions, offering seamless remote desktop access for IT support, remote work, and personal assistance. However, encountering a “AnyDesk not working” issue on Windows 11 can be incredibly frustrating, especially when you urgently need to connect.

This comprehensive guide is designed not just to list solutions, but to help you understand why the problem occurs and systematically apply the correct fix. We’ll cover everything from basic checks to advanced network configurations, ensuring you regain control of your remote sessions.

Why Does AnyDesk Stop Working on Windows 11?

Before diving into fixes, understanding common culprits helps target your troubleshooting. Windows 11 introduced new security features, networking stacks, and system architecture that can sometimes clash with remote access software.

Windows Security & Firewall: Windows 11’s enhanced security often blocks unfamiliar connections.
Outdated Software: Incompatibility between an old AnyDesk version and the latest Windows 11 updates.
Permission Issues: User Account Control (UAC) and admin rights can prevent proper operation.
Network Configuration: Complex firewalls, VPNs, or incorrect network profiles can disrupt the connection.
Corrupted Installation: Local application files or settings may become damaged.

Let’s methodically work through these issues, starting with the simplest solutions.

Step 1: The Essential First Checks (5-Minute Fixes)

Always rule out the obvious first. These steps resolve a significant percentage of reported issues.

Restart Your Computer: It’s cliché for a reason. A simple restart refreshes system processes, clears temporary glitches, and re-establishes network connections. Restart both the local and remote computers.
Check Your Internet Connection: AnyDesk requires stable internet on both ends.
- Run a speed test on websites like Fast.com or Speedtest.net.
- Try accessing other websites or online services to confirm general connectivity.
Verify the AnyDesk Address & Password: Double-check the 9-digit AnyDesk address on the remote machine. If using a password, ensure it’s entered correctly. Consider using a temporary one-time password for testing.

Step 2: Grant AnyDesk Permission Through Windows Security

Windows Defender Firewall is a primary gatekeeper. AnyDesk needs explicit permission.

A. Allow AnyDesk Through the Firewall:

Search for “Windows Security” in the Start menu and open it.
Go to Firewall & network protection > Allow an app through firewall.
Click Change settings (admin rights required).
Find AnyDesk in the list. If it’s not there, click Allow another app…, browse to the AnyDesk installation folder (typically C:Program Files (x86)AnyDesk), select AnyDesk.exe, and add it.
Ensure both Private and Public boxes are checked for AnyDesk.
Click OK.

B. Disable Antivirus Temporarily (For Testing):
Third-party antivirus suites (like McAfee, Norton, or Kaspersky) can be more restrictive. Temporarily disable your antivirus real-time protection and try connecting. Remember to re-enable it immediately after testing. If this works, add AnyDesk to your antivirus exception/allow list.

Step 3: Update or Reinstall AnyDesk

Running outdated software is a common cause of compatibility issues.

Update AnyDesk:

Open AnyDesk.
Go to Settings (the gear icon).
Navigate to About.
Click Check for new version. If an update is available, install it.

Perform a Clean Reinstall:
If updating doesn’t help, a clean reinstall removes corrupted files.

Press Win + I, go to Apps > Installed apps.
Find AnyDesk, click the three dots, and select Uninstall.
Crucial Step: After uninstalling, delete the AnyDesk residual folders:
- C:Program Files (x86)AnyDesk
- C:Users[YourUsername]AppDataRoamingAnyDesk
- C:ProgramDataAnyDesk (This folder is hidden; type the path directly in File Explorer’s address bar).
Download the latest version directly from the official AnyDesk website.
Install the freshly downloaded file and run as administrator.

Step 4: Adjust Network Discovery & Sharing Settings

Windows 11 uses “Network Profiles” (Private vs. Public) that control discovery.

Set Your Network to Private (If Appropriate):
A Public network profile is more restrictive and can block AnyDesk.

Go to Settings > Network & internet > Ethernet/Wi-Fi.
Click on your active network connection.
Under Network profile type, select Private. (Only do this on trusted networks like your home or office).

Enable Network Discovery:

Open the Control Panel (search for it in Start).
Go to Network and Sharing Center > Advanced sharing settings.
Expand your current profile (Private).
Ensure Turn on network discovery and Turn on file and printer sharing are selected.
Click Save changes.

Step 5: Run AnyDesk with Administrator Privileges

Some actions, like installing the AnyDesk service for unattended access, require elevated rights.

Right-click the AnyDesk shortcut on your desktop or Start menu.
Select Run as administrator.
For permanent admin rights, right-click the shortcut > Properties > Compatibility tab > Check Run this program as an administrator.

Step 6: Configure Advanced AnyDesk & Windows Settings

If problems persist, delve into these specific settings.

A. Change the Listening Port in AnyDesk:
Corporate firewalls often block non-standard ports. AnyDesk defaults to port 7070 (TCP). Try changing it.

In AnyDesk, go to Settings > Connections.
Under Listening Port, uncheck Use default port.
Enter a common port like 80 (HTTP) or 443 (HTTPS). You must set this on both the client and remote machine.
Restart AnyDesk.

B. Disable IPV6 (Troubleshooting Step):
Dual-stack networks (IPV4/IPV6) can sometimes cause connection hiccups.

Press Win + R, type ncpa.cpl, and press Enter.
Right-click your active network adapter and select Properties.
Uncheck the box for Internet Protocol Version 6 (TCP/IPv6).
Click OK and restart your computer. Test AnyDesk. (Remember to re-enable IPv6 later if it doesn’t solve the issue, as it’s an important internet standard).

C. Check for Windows Updates:
Microsoft frequently releases patches that can affect software compatibility.

Go to Settings > Windows Update.
Click Check for updates and install all available updates, especially optional driver updates.
Restart your PC after updating.

Step 7: Diagnose Specific Error Messages

Sometimes AnyDesk provides a clue. Here are fixes for common errors:

“Connection refused” or “No route to client”: Almost always a firewall/antivirus block on the remote machine. Revisit Step 2 on the remote PC.
“Client not found” or “Address not valid”: The remote AnyDesk is not running, or the address was entered incorrectly. Verify the remote app is open and the 9-digit ID is correct.
Black Screen upon Connection: This is often a graphics driver or display issue.
- Update your graphics drivers from NVIDIA, AMD, or Intel’s website.
- In AnyDesk on the remote PC, go to Settings > Display and try changing the Video adapter setting.
AnyDesk Crashes on Startup: Likely a corrupt installation or system file conflict. Perform the Clean Reinstall (Step 3) and run a System File Checker scan (sfc /scannow in an admin Command Prompt).

Advanced & Last Resort Solutions

1. Flush DNS & Reset Network Stack:
Network cache corruption can block connections.

Open Command Prompt as Administrator.
Run these commands one by one, pressing Enter after each:
- ipconfig /release
- ipconfig /flushdns
- ipconfig /renew
- netsh winsock reset
Restart your computer.

2. Perform a Clean Boot:
This identifies if background software is causing the conflict.

Press Win + R, type msconfig, and press Enter.
Go to the Services tab, check Hide all Microsoft services, then click Disable all.
Go to the Startup tab, click Open Task Manager, and disable all startup items.
Click OK and restart. If AnyDesk works now, re-enable services/startup items in batches to find the culprit.

Conclusion: Regaining Control

Troubleshooting “AnyDesk not working in Windows 11” is a process of elimination. Start with the basic permissions and updates, then move to network and advanced settings. In most cases, the issue is resolved by allowing AnyDesk through the Windows Firewall, updating the software, or performing a clean reinstall.

FAQ Section (Structured for Readability)

Q1: Why does AnyDesk keep saying “Connection refused” on Windows 11?
A: This is almost exclusively a firewall or antivirus issue. The remote computer’s security software is actively blocking the incoming AnyDesk connection. You must add AnyDesk as an exception in Windows Defender Firewall and any third-party antivirus on the remote machine.

Q2: Is AnyDesk fully compatible with Windows 11?
A: Yes, AnyDesk is officially compatible with Windows 11. However, compatibility depends on having the latest version of AnyDesk installed. Always ensure you’ve downloaded the most recent version from the official website after a major Windows update.

Q3: How do I allow AnyDesk through my corporate firewall?
A: You will likely need to contact your IT department. Provide them with the necessary port information (default is TCP 7070, but it can be changed to 80 or 443). They need to create an outbound rule on your local firewall and potentially an inbound rule on the remote network’s firewall.

Q4: Can a VPN interfere with AnyDesk?
A: Absolutely. VPNs route all your traffic through a separate server, which can disrupt the direct peer-to-peer connection AnyDesk tries to establish. If you need both, try connecting the AnyDesk session first, then enable the VPN, or vice versa. Alternatively, configure your VPN to allow local network traffic (split tunneling).

Q5: What should I do if none of these solutions work?
A: As a last resort, you can try using AnyDesk’s built-in “TCP Tunneling” mode (found in Settings > Connections), which can bypass certain network restrictions. If the problem persists, visit the official AnyDesk Support Center for more specialized help or to contact their technical team.
