 Native Win32 driver client targeting Windows XP-era systems.
 
-The client authenticates with `https://auth.xtransit.testinstance.nl`, then requests
-assigned weekly schedule templates from
-`https://transit.xtransit.testinstance.nl/driver/schedules/daily`.
+For Windows XP compatibility, the client temporarily uses the LAN services:
+
+- Login: `http://192.168.68.66:5000/login`
+- Assigned schedules: `http://192.168.68.66:5001/driver/schedules/daily`
+- Route stops: `http://192.168.68.66:5001/bus-lines/:busLineId/stops`
+
+This HTTP fallback avoids the TLS 1.2/certificate limitations of Windows XP.
 
 Schedules are assigned through `transit.shifts`; the client does not expect a
 `driver_id`, `bus_id`, or `weekdays` column on `transit.schedules`.

+If the app shows `Driver service unreachable`, open `driver_xp.log` in the same
+folder as the installed `driver_xp.exe` and inspect the latest entries. The log
+records the failing stage and WinHTTP or HTTP status code, but never writes the
+password or JWT token.

+Common codes:
+
+- `12007`: hostname could not be resolved (DNS)
+- `12029`: connection to the server failed
+- `12175`: HTTPS certificate or TLS validation failed
+- `401` or `403`: the server responded, but authentication was rejected
