# Troubleshooting

> Resolve the most common issues in a few minutes.

If something isn't working as expected, start here. Most issues fall into a few common categories and can be resolved in a couple of minutes.

## A source stopped syncing

The most common cause is expired or changed credentials. Open the connections list, find the source flagged for attention, and re-enter its details. If the problem persists, confirm the environment is reachable from your network.

> **Tip:** The connections list always shows the last successful sync time, which is the fastest way to spot a source that has quietly fallen behind.

## A dashboard looks empty

Newly connected sources take a short time to complete their first sync. If a dashboard is empty right after setup, give it a few minutes and refresh. If it's still empty, check that the source connected successfully in the [How to Connect Devices](https://visualoneintelligence.com/docs/) guide.

## Still stuck?

Reach out to your account team with a short description of what you're seeing and, if possible, the name of the affected source. That's usually enough for us to pinpoint the issue quickly.
