When your VPN suddenly stops working, it's frustrating—but usually fixable. Whether you're blocked from streaming, seeing connection errors, or just getting slow speeds, these troubleshooting steps will get you back online fast.
Quick Fixes That Work 90% of the Time
- Switch servers – Your current VPN server might be overloaded or blocked. Try 2-3 different locations.
- Restart everything – Close your VPN app, reboot your device, then reconnect.
- Check your internet – Disconnect the VPN and test if your base connection works at Fast.com.
- Update the app – Outdated VPN clients often fail silently. Check for updates in your app store.
- Try a different protocol – Switch from OpenVPN to WireGuard (or vice versa) in your VPN settings.
Clean Setup for Stubborn Cases
- Uninstall your VPN completely (don't just delete the app—use the provider's removal tool if available)
- Restart your device
- Download a fresh copy from your provider's website (not an app store)
- Install using default settings
- Connect to a recommended server (not “auto-connect”)
Still stuck? Some ISPs aggressively block VPNs. Try ExpressVPN‘s obfuscated servers (labeled “Stealth” in settings) which disguise VPN traffic as regular HTTPS.

VPN Troubleshooting FAQs
Why does my VPN keep disconnecting?
Usually due to unstable internet, aggressive firewalls, or battery-saving modes on mobile. Try switching to a more stable protocol like WireGuard, and disable battery optimization for your VPN app.
Netflix detects my VPN—how to fix?
Streaming services actively block VPN IPs. Use ExpressVPN or NordVPN which refresh their streaming-optimized servers frequently. Clear your browser cache after connecting.
My VPN slows my internet to a crawl
This often means protocol mismatch. If using OpenVPN, switch to UDP instead of TCP. Better yet, use WireGuard-based protocols like NordLynx (NordVPN) or Lightway (ExpressVPN).
Can my ISP completely block VPNs?
They can try, but modern VPNs use obfuscation to bypass blocks. In restrictive countries, stealth VPNs work best. Some providers offer “Tor over VPN” as a last resort.
