What Happened?

The traffic usage reporting in all versions of Hiddify clients is significantly inaccurate. When downloading a file of ~200MB, the client (as well as panel & subscription link stats) only shows around 20MB consumed.
Additionally, some services (like Telegram, general downloads, and most websites) show zero traffic usage, while some (e.g., YouTube) report minimal usage but still far less than actual.

Even though traffic is being consumed on the server side (as confirmed via server monitoring), client apps and the management panel do not reflect the actual bandwidth usage. This makes traffic accounting unreliable, both for end-users and administrators.

Minimal Reproducible Example (MRE)

Connect to Hiddify via Windows, iOS, or Android client

Download a large file (e.g., ~200MB from a random site)

Check data usage in:

Hiddify client

Subscription link stats

Management panel

Repeat the test with YouTube, Telegram, and Instagram

Note the discrepancies (or zero usage in some cases)

Expected Behavior

I expect accurate traffic usage tracking across:

Hiddify clients

Management panel

Subscription link statistics

All types of traffic (downloads, streaming, social media) should be counted properly regardless of protocol or destination.

Additional Context

My entire user base is using configurations generated by Hiddify Panel with the same issue across clients.
Server-side traffic is verifiably consumed but neither clients nor admin stats reflect it.
The issue persists even on multiple versions and platforms.

Application Config Options

Please let me know if you need my full panel config or specific settings, I can provide on request.

Relevant log output

I don't have specific logs right now, but I can reproduce the issue and provide client/server logs if required.
