Check Firewall Modules: Verify if your firewall can handle VPN traffic. Temporarily disable it if necessary.
Consider Plug-Ins and Software: Look for any software that blocks VPN traffic and disable it.
Contact Firewall or Router Support: Check with your router or firewall for issues that might be blocking your connection.
Review VPN Provider Issues: Contact their customer support to confirm if there's a problem with their service.
Check Account Settings: Ensure your account is up-to-date and correctly configured.
Try a Different VPN Service: If your current service isn't working, try a different provider to see if it resolves the issue.
