  • Cause: DNS leaks or improperly configured VPN.
  • Solution: Enable DNS leak protection on your VPN client and ensure it's properly set up.

Troubleshooting Common VPN Issues

Connection Failure

If you encounter connection failure, first check your internet connection. It's like trying to make a phone call without signal bars - you need a stable connection to establish a VPN connection. Restarting your router is like giving your internet a quick refresh, just like rebooting your phone when it's acting up. And verifying your VPN settings is similar to double-checking the recipient's number before making a call.

Slow Connection Speed

Experiencing slow speed after connecting to a VPN is frustrating. It's like driving on a congested highway during rush hour - too many cars (users) on the road (server) can slow down your journey (internet speed). Trying a different server is like taking an alternative route to avoid traffic jams. Upgrading your VPN plan is akin to choosing a faster car (higher bandwidth) for a smoother ride.

IP Address Leaks

IP address leaks defeat the purpose of using a VPN for privacy. It's like wearing a disguise at a masquerade ball but accidentally revealing your face. DNS leaks are like leaving breadcrumbs that lead back to you. Enabling DNS leak protection is like ensuring your disguise is foolproof, and configuring your VPN properly is like making sure your mask stays on securely.
