Ookla Speedtest can always detect my isp

Greeting folks,

I am running using a reputable vpn service (one that allows you to pay by cash and or crypto, is hw in Switzerland and has a solid reputation for privacy).

When performing a speed test using the Ookla app (Android 14), the speedtest app always recognizes my isp. I have tested for DNS and WebRTC leaks, I have tried openvpn, wireguard and the proprietary protocol provided by my vpn service.

I have wiped the application and all cache and trace files, I do my speedtests without an ookla account.

I have both kill switch and block non vpn traffic enabled. Regardless of this, when opening speedtest app it immediately recognizes my true isp.

Any advice would be appreciated

Same Problem by me. But only if i using my mobile data.

They say it in the app, the app rembers where you been and just uses that, it’s just so you can get more accurate results
