VPN works on Wi-Fi but not LTE
If the unchanged profile works on Wi-Fi but fails on mobile data on the same device, the configuration is broadly valid. The difference is commonly in DNS, carrier routing, IP reachability, or transport handling.

Controlled test
- Verify mobile internet with VPN disabled.
- Disable Private DNS only for diagnosis.
- Test one profile and record the exact time.
- Repeat the unchanged profile on Wi-Fi.
- Test a second subscription location on mobile data.
Interpretation
Wi-Fi success rules out many UUID and server configuration errors, but does not prove mobile reachability. If every location fails only on LTE, inspect DNS and app restrictions. If one address fails, its route or subnet is more likely involved.

The review uses developer documentation and reproducible service diagnostics.
