Hey, thanks for the report - great diagnostics.
This is a known issue with the build pipeline - the embedded commit hash in the cursor-tunnel doesn’t match what’s on the CDN. The same situation happened a week ago with another commit: Cursor serve-web fails to download server - commit hash mismatch
The team is aware through the existing ticket. This is a recurring bug - it first appeared back in July and auto-closed without a solution.
Your report will add another failing commit hash to the diagnostics - that helps.
Unfortunately, there’s no ETA, and the workaround through SSH + Termux (which you’re already using) is currently the only option for mobile access.
Keep an eye on the thread above. I’ll provide an update if there’s any progress.
