## Why it happens

Sinch's Number Lookup v2 reuses HTTP codes with Sinch-specific meanings. Reading them as generic HTTP codes misdiagnoses the problem.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
