Interactive tool
VPN troubleshooting wizard.
Choose the problem and device type, then get issue-specific checks, platform notes, commands where useful, and an explanation of what each step proves.
What does this tool do?
This wizard does not run a remote VPN test for you. Instead, it builds a practical checklist based on the problem and platform you choose. The output explains what each check proves, whether you should focus on DNS, public IP, routing, protocol choice, browser cache, streaming region or local network issues.
For Linux, Windows and macOS it also includes useful commands. For mobile and router setups, it gives system setting checks instead.
