Troubleshooting

First stop for "something isn't right." If none of these match your situation, the Support card on the Status page has a Download diagnostic bundle button — send the resulting zip to your Padas contact.

The desktop shortcut doesn't open anything

Open a browser yourself and type http://localhost:47823 into the address bar.

  • Page loads: the shortcut file's URL is out of date. Right-click the shortcut → Properties → check the URL. Should read http://localhost:47823/. If not, delete the shortcut and reinstall the service (or wait for the next update — the service rewrites the shortcut on every update).
  • Page doesn't load: the service isn't running, or it's running on a different port. Check the Service Manager: press Win + R, type services.msc, look for "Gundi Radio Service." It should be Running. If it's Stopped, right-click → Start. If starting fails, the Event Viewer's System log has the SCM error.

Status page says "Not configured"

The pump's idle-on-error state. Click the Set up the service button to open the wizard, or head to the Configuration page if you've used it before.

Status page shows the pump as Running but no batches appear

A few possibilities. In rough order of likelihood:

The database has no recent data. If "Last batch" shows a very old timestamp or "(never)," and no errors are logged, the pump is healthy but the source database hasn't received any new records the pump is interested in. Check the dispatch console: are radios actively reporting?

The database is slow on the first query. The pump's initial poll fetches the most recent two days of records. On a large unindexed table, that can take longer than the configured timeout (default 5 minutes). The log line is Database error (attempt N/5) with a Timeout exception. The fix is on the database side — usually adding an index on the timestamp column the pump filters by. Download the diagnostic bundle (Status page → Support card) and send it to your Padas contact; a support tech can confirm and provide the exact SQL for your database.

Group filters exclude everything. If "Send all observations" is off and your alias list is wrong (a GUID typo, or filters for a group that has no records), the pump will run silently with no posts. Check the Configuration page → destinations → group aliases.

Gundi API key is rejected. The log line is 401 Unauthorized or similar from GundiV2DataWriter. The Configuration page's Test API key button surfaces this explicitly. Re-paste the key from your Gundi project page.

Update flow stalled

If you clicked Update to X.Y.Z and the page didn't recover after a couple of minutes:

  1. Refresh the browser tab. The reconnection modal usually shows; click its Refresh button. If the modal doesn't appear, press F5 manually.
  2. Check the service is running. Open Service Manager (services.msc) and look for "Gundi Radio Service." Should be Running. If Stopped, right-click → Start.
  3. Look at apply.log. Lives at C:\Program Files (x86)\GundiRadioService\apply.log. The last line should read "Package version X.Y.Z applied successfully." If it shows a different error or the file is older than your click, the update step itself failed. Send the file to your Padas contact.

"Windows protected your PC" on install

Expected. The installer isn't yet code-signed. Click More info → Run anyway. If you're worried about the authenticity of the download, the URL https://storage.googleapis.com/radio-connectors/velopack/GundiRadioService-win.msi is HTTPS-served from Google Cloud Storage and Padas publishes exclusively to that bucket.

I want to remove the service

Use the standard Windows path: Settings → Apps → Installed apps → find "GundiRadioService" → Uninstall. This stops the service, removes the binaries, removes the desktop shortcut, and unregisters the service from SCM.

What it does not remove:

  • C:\ProgramData\GundiRadioService\ — operator config and cursor state. Left intact so a reinstall picks up where you left off.
  • The downloaded MSI in your Downloads folder (delete manually if you want).

If you want a fully clean wipe, delete C:\ProgramData\GundiRadioService\ by hand after uninstall.

Something else

The Status page's Support card has a Download diagnostic bundle button. It builds a zip containing:

  • The current log file.
  • Archived log rolls (older history).
  • A redacted copy of the operator config (no passwords or API keys).
  • The cursor state file.
  • A metadata file with version, machine name, OS, and a snapshot of pump status at bundle time.

Email it to your Padas support contact with a brief description of what you observed. The bundle has everything we need to diagnose remotely.
