6 Easy Ways to Fix UltraSurf if it's not Working

UltraSurf is a freely available app for securing browsing with proxy connections. That software enables users to bypass geographical browsing restrictions. UltraSurf is similar to VPN software, but it only encrypts HTTPS traffic.

However, sometimes users might not be able to connect with Ultrasurf. When the UltraSurf status is not connected, you might need to check some settings. The potential resolutions below might fix an UltraSurf connection.

What is UltraSurf’s platform compatibility?

UltraSurf is compatible with the Windows, Android, and iOS platforms. Thus, you can utilize it on Windows PCs and Android and iOS mobile devices. However, don’t be surprised when UltraSurf doesn’t work on Apple and Linux desktop platforms.

What are the best browsers for UltraSurf?

UltraSurf has primarily been designed for Internet Explorer and Google Chrome. Therefore, it’s best to utilize UltraSurf with those browsers. However, you can still use it with some alternative browsers.

Quick Tip:

Instead of utilizing UltraSurf for Chrome and Internet Explorer, why not use a browser with a built-in VPN instead? Opera is perhaps the most notable browser that incorporates its VPN. That built-in VPN also conceals locations so its users can bypass geo-content restrictions.

Opera also has many other fine features. Its customizable speed dials on its start page are one of Opera’s standout features.

Opera’s unique sidebar with built-in messengers and a built-in music player is another great addition. My Flow is also a great Opera sidebar feature for sharing web content.

Pick a valuable browser with an improved security proxy and built-in VPN protection.

How can I fix UltraSurf not working (connecting)?

1. Run the Internet Connections troubleshooter

1. Press the Windows key + I to open the Settings app and select Update & Security.
   
2. Choose Troubleshoot in the left pane and click Additional troubleshooters.
   
3. Now, select Internet Connections and click Run the troubleshooter.
   

The Network Adapter troubleshooter might also come in handy for resolving UltraSurf connection issues.

2. Select a different server

UltraSurf includes three different server checkbox options for users to select from. The best server is usually determined by default, but alternative options exist. So, choose one of the other server options when UltraSurf doesn’t connect.

3. Turn off Windows Defender Firewall

1. Press the Windows key + S, type fire, and click Windows Defender Firewall.
   
2. Choose to Turn Windows Defender Firewall on or off in the left pane.
   
3. Now, select the radio buttons for Turn off Windows Defender Firewall (not recommended) options for both the Private and Public networks.
4. Finally, click OK to exit the window.
   

Another effective solution if Ultrasurf is not working is to disable your firewall. However, It’s recommended to turn your firewall back on whenever you are not browsing the web with UltraSurf connections.

4. Uninstall third-party antivirus software and firewalls

1. Press the Windows key + R, type appwiz.cpl, and click OK.
   
2. Next, select any third-party antivirus software and firewall you have installed.
3. Finally, click the Uninstall option and follow the onscreen instructions to complete the process.
   

Sometimes, Ultrasurf might not work because your antivirus software is blocking it. In this case, you can try to disable the software to see if that solves the problem.

You should remove the antivirus from your PC if that does not work. To make sure you remove all the components of the antivirus, it is recommended that you use a dedicated third-party uninstaller software in CCleaner to complete the process.

This top-notch tool will ensure there is no stubborn leftover file that can cause problems later.
