Short answer: A useful VPN troubleshooting flow starts before the VPN connects, records the visible IP/DNS/WebRTC/IPv6 state, connects the VPN, retests, then uses Safe Copy. This separates normal VPN routing from DNS mismatch, WebRTC exposure, IPv6 behavior, and device-specific setup problems.
Use this hub when a VPN is installed but the result is unclear: IP still shows, DNS country differs, streaming devices use router VPN, iPhone disconnects, or kill switch behavior needs a practical check.
Quick answer
- Start with VPN Leak Test because it is the main tool for this topic.
- Compare the result with adjacent signals instead of treating one test as a full privacy guarantee.
- Use the guide list below to move from diagnosis to the next practical fix.
- Use Safe Copy after testing so you can compare before and after without sharing sensitive raw details.
VPN Setup & Troubleshooting at a glance
| Signal | What it means | Best next step |
|---|---|---|
| Before state | Your normal IP, DNS, WebRTC, IPv6, and browser signals before VPN. | Save the baseline first. |
| Connected state | What changes after the VPN connects. | Run VPN Leak Test again. |
| IP still shows | The visible IP may be the VPN endpoint or the original ISP route. | Compare network owner, ASN, and expected country. |
| DNS mismatch | DNS can differ because of browser Secure DNS, router DNS, ISP DNS, or VPN DNS. | Run DNS Leak Test after the VPN check. |
| WebRTC/IPv6 | Browser candidates and IPv6 can behave differently from the page IP. | Run WebRTC and IPv6 tests as follow-ups. |
| Receipt | A safe receipt makes support or personal troubleshooting easier. | Use Safe Copy after re-test. |
Limits and methodology
MyIPScan topic hubs organize practical checks around observable browser and network signals. Results are snapshots for this browser, device, network, and time. They do not prove full anonymity, do not replace provider documentation, and do not test every app on the device.
