VPN Troubleshooting 101: Fix Common Issues in Minutes

Published on 25 March 2025 at 21:00

Even the best VPNs can hit snags—slow speeds, connection drops, or sudden leaks. But don’t panic! Most VPN issues are quick to fix if you know where to start. In this guide, we’ll walk you through common VPN problems and their solutions, so you can get back to secure browsing, streaming, or gaming.

1. "My VPN Won’t Connect"

Why It Happens:

  • Server overload (too many users on one server).

  • Outdated VPN app.

  • Firewall or antivirus blocking the connection.

  • Incorrect login credentials.

How to Fix It:

  • Switch Servers: Choose a less crowded server.

  • Update the App: Check for updates in your VPN’s settings.

  • Disable Firewall/Antivirus Temporarily: Test if they’re interfering (re-enable afterward!).

  • Reset Your Password: Use the “Forgot Password” link if you’re locked out.

  • Change Protocols: Try switching from OpenVPN to WireGuard (or vice versa) in your app’s settings.

Pro Tip: If all else fails, uninstall and reinstall the VPN app.


2. "My VPN Is Slow"

Why It Happens:

  • Distance between you and the VPN server.

  • Heavy encryption overhead.

  • ISP throttling (yes, even with a VPN!).

How to Fix It:

  • Connect to a Nearby Server: Reduce latency by picking a server closer to your location.

  • Use a Faster Protocol: Switch to WireGuard or Lightway (faster than OpenVPN).

  • Split Tunneling: Bypass the VPN for non-sensitive apps (e.g., gaming) to save bandwidth.

  • Test Different Times: Avoid peak hours when servers are busiest.

Pro Tip: Run a speed test without the VPN first to rule out general internet issues.


3. "My VPN Keeps Disconnecting"

Why It Happens:

  • Unstable internet connection.

  • Battery-saving modes on mobile devices.

  • VPN server instability.

How to Fix It:

  • Enable the Kill Switch: This blocks internet access if the VPN drops, preventing leaks.

  • Disable Battery Optimization: On phones, go to Settings > Battery > turn off optimization for your VPN app.

  • Use a Wired Connection: Wi-Fi drops? Plug into Ethernet for stability.

  • Restart Your Router: A classic fix for flaky internet.


4. "Netflix/Streaming Services Don’t Work with My VPN"

Why It Happens:

  • Streaming platforms actively block VPN IP addresses.

How to Fix It:

  • Try a Different Server: Some servers are less likely to be flagged. Look for ones labeled “Streaming.”

  • Clear Browser Cache and Cookies: Sites track your location via cookies—wipe them out.

  • Use Obfuscated Servers: These hide VPN traffic, making it look like regular browsing (available in apps like NordVPN and ExpressVPN).

  • Contact Support: Ask your VPN’s team which servers work best for streaming.


5. "I’m Experiencing DNS Leaks"

Why It Happens:

  • VPN fails to route DNS requests through its encrypted tunnel.

  • Misconfigured settings.

How to Fix It:

  • Enable the VPN’s Built-In DNS: Check your app’s settings for DNS leak protection.

  • Run a DNS Leak Test: Use DNSLeakTest.com to confirm the fix.

  • Switch Protocols: Some protocols (like WireGuard) handle DNS more securely.

Pro Tip: Avoid custom DNS settings (e.g., Google DNS) while using a VPN.


6. "My VPN Blocks Websites or Apps"

Why It Happens:

  • Overzealous VPN firewall rules.

  • Conflicts with local network policies (common in schools or offices).

How to Fix It:

  • Disable the VPN Firewall: Look for settings like “CyberSec” (NordVPN) or “Threat Protection” (Surfshark) and toggle them off.

  • Try Split Tunneling: Exclude the problematic app from the VPN tunnel.

  • Use a Different Server/Protocol: Some servers may have fewer restrictions.


7. "I Can’t Log In to My VPN Account"

Why It Happens:

  • Expired subscription.

  • Too many simultaneous connections (exceeded device limit).

  • Server authentication issues.

How to Fix It:

  • Check Your Subscription Status: Renew if expired.

  • Log Out of Other Devices: Free up slots by disconnecting unused ones.

  • Use a Different Network: Switch from Wi-Fi to mobile data to rule out network blocks.


When to Contact Your VPN’s Support Team

If none of the above works, reach out to your provider. They can:

  • Diagnose server-side issues.

  • Share advanced settings (e.g., manual configuration files).

  • Escalate bugs in the app.

Pro Tip: Have your OS version, VPN app version, and error messages ready for faster help.


Prevent Future Issues: Best Practices

  1. Keep Your VPN App Updated.

  2. Use the Kill Switch Always.

  3. Stick to Reputable Providers with 24/7 support.

  4. Regularly Test for Leaks (IP, DNS, WebRTC).
