•  If none of these steps solves the issue, it is time to contact your internet service provider for further assistance.
• Also, check your VPN provider’s website for possible troubleshooting tips.

Why is my VPN so slow?

1. Check system resources

If you’re frustrated with the slow performance of your VPN, you’ve come to the right place. The first step in fixing the issue is to check your system’s resources. If too many processes are running on your computer, this might be a factor.

2. Run speed test

Close all those unnecessary programs and reboot your computer, then try running a speed test. If the results show that your VPN is slow, your connection may be slow as well. Speed Test tool should be used before connecting to a server so that they can find the most suitable server that performs well for your ISP. AstrillVPN offers a built-in speed test tool that allows users to check the performance of the VPN servers. They conduct daily tests using Speedtest.net to ensure smooth operation and to identify any potential issues. This ensures that there is ample bandwidth available for all users without any speed restrictions.

If you’re interested in testing for potential VPN leaks, AstrillVPN also has a VPN leak test tool available on their website, which can help you ensure your online privacy and security. 

3. Switch to UDP or TCP protocol

Another possible cause of a slow VPN is the protocol it uses to transmit data. Try using TCP or UDP instead. Try changing to another VPN protocol, such as OpenWeb. If both still seem to be slow, the VPN provider may need to be utilizing server load-balancing techniques properly, or their network connections need to be improved.

4. Contact VPN Provider

Contact AstrillVPN’s customer support if you’re experiencing persistent ISP restrictions or throttling issues. They may have specific recommendations or alternative server configurations to help you overcome these limitations.

To determine if this problem is related to AstrillVPN, read AstrillVPN documentation. AstrillVPN is providing detailed guidelines on their pricing plans and all resolved issues. 

Why is VPN not working on the Desktop?

1. Fix the connection

If your VPN isn’t connecting on your Mac or iOS device, try to fix the connection first. Check your network settings. Your network filtering may block your VPN connection. If so, you should contact your ISP and perform some troubleshooting steps.

2. Try an alternative routing feature

If you’re in a restrictive country, try using the alternative routing feature to bypass the blocking. Resetting your router may also fix the problem. If these steps don’t work, try restarting your computer.

3. Check for the latest version

VPN software sometimes has bugs or glitches. To fix this, ensure you have the latest version. Make sure you’re using a premium VPN provider, as they test their software constantly. If the problem persists, try resetting your VPN software or re-installing it.

4. Clean disk space

Clear disk space and closing background apps may solve the issue. If none of those options work, try trying a different server. If you are an Astrill user, go to Settings > Astrill VPN > Repair.

VPN not connecting on the phone

If your VPN is not connecting, you have two options. You can contact customer support and ask for help. Ideally, you should go for a live chat, but if it is too complicated to solve online, you can also send a detailed ticket.

1. Astrill connection issue

 If you cannot connect from a mobile phone, check AstrillVPN servers, and you can connect within a few seconds. You can type server IP instead of address by finding your desired server. If the error persists, disable the ISP proxy in settings. Also, if you cannot connect, you should try to change a server. VPN customer support teams are available 24/7 to assist you.

If your VPN app is not connecting to the internet on Android, you may be experiencing a problem related to the Windows subsystem for Android. The issue is not related to the version of the phone but rather to other issues related to the VPN tool you are using.

2. Check DNS settings

Third-party antivirus solutions, DNS settings, and your network preference may also be contributing to the problem. To fix the issue, you should perform a few simple steps as detailed below:

• Update your browser. Whenever your VPN app isn’t connecting, you should first try to update your browser. The process is similar to updating the VPN app.
• To do this, navigate to the list of installed applications on your phone and select it.
• From there, decide which app you want to keep and which one you want to delete.
• After that, tap the icons that you wish to uninstall and drag them to the Trash icon.

Why is VPN not connecting to the router?

One of the most common causes of a VPN not connecting to your router is a double NAT problem. This problem occurs when a router is on the same network as the VPN, so a simple solution is to enable bridge mode on both devices.

• To activate bridge mode, follow the documentation that came with your router to make sure it is enabled.
• Another possible cause of a VPN not connecting is a problem with your DNS server. VPNs usually supply their own DNS services when connecting, so your DNS settings will vary from one provider to another.
• Some VPN providers block traffic on specific ports, so changing the port to an unblocked one may be a good idea.
• Also, if your ISP doesn’t allow VPN passthrough, you should try setting up your router as administrator. Some routers don’t support this option, so you must do this manually.
• Sometimes, the problem can also lie with your ISP, so you may need to contact customer support to ask them to change the settings.

ISP Restrictions and Throttling

Internet Service Providers (ISPs) can sometimes impose restrictions or implement throttling techniques that affect VPN connections. These measures are typically implemented for various reasons, such as network management, complying with legal requirements, or limiting access to specific services. Here’s an explanation of ISP restrictions and some workarounds to overcome these limitations:

Understanding ISP Restrictions

ISPs may actively block or restrict VPN connections to control network traffic or enforce policies. They can identify VPN traffic by examining packet headers and ports or using deep packet inspection (DPI) techniques. Some ISPs may also limit access to VPN services to promote their own security or privacy solutions.

Fixing ISP Restrictions

1.   Change VPN Protocols

ISPs often target specific VPN protocols for blocking or throttling. Switching to an alternative protocol, such as OpenVPN, OpenWeb, or WireGuard, may help bypass such restrictions. Experiment with different protocols offered by AstrillVPN.

2.   Use Obfuscation or Stealth Mode

Astrill offers obfuscation or stealth features that help disguise VPN traffic as regular encrypted traffic. This can make it more challenging for ISPs to detect and throttle your VPN connection.

3.   Try Different VPN Servers

If your ISP targets specific VPN server IP addresses, try connecting to alternative servers provided by AstrillVPN. By switching to different server locations, you can find servers not actively blocked or throttled by your ISP.

4.   Port Forwarding

Some VPN providers offer port forwarding as an option. You can route VPN traffic through non-standard ports by enabling port forwarding, making it harder for ISPs to identify and throttle your VPN connection. AstrillVPN supports port forwarding, and you can follow this SSH port forwarding guide to configure AstrillVPN port forwarding easily.

5.   Use a VPN with Stealth/Obfuscation Protocols

Consider using a VPN service that specializes in bypassing restrictions. AstrillVPN employs advanced techniques to circumvent ISP restrictions and maintain a stable VPN connection through its Stealth VPN feature. Therefore, choose AstrillVPN as it has the ability to overcome blocking or throttling.

6.   Consult with Your VPN Provider

Contact AstrillVPN’s customer support if you’re experiencing persistent ISP restrictions or throttling issues. They may have specific recommendations or alternative server configurations to help you overcome these limitations.

Conclusion

By successfully resolving VPN connection problems, you can enjoy the numerous benefits of using a VPN, including enhanced online security, privacy, and unrestricted access to online content. Encountering issues with VPN connections can be frustrating, but you can overcome most obstacles by understanding the common causes and implementing troubleshooting techniques.

Remember, if you continue to experience persistent issues or need further assistance, reaching out to AstrillVPN’s customer support, which will provide valuable insights and tailored recommendations.
