# Troubleshooting
### Troubleshooting your Edge
After publishing your configuration, the status will attempt to connect to your supplied datasources and read tag addresses. In the event that any of these fail, the edge will report back with an error of what went wrong. This error is displayed in the status column of the edge and is represented by a symbol representing:
* **Green tick** - No Errors, everything working.
* **Blue Exclemation** - Either the edge has not yet reported the status or you still need to publish the configuration
* **Red Exclemation** - An error has occured on either this item or an item below it. Hover over the symbol to see the error message
The status symbol will not only display errors for itself, but also the errors that are inside of it. For example, a tag failed to be read, the datasource and the tag will display the error message.
Another way of troubleshooting your edge is by reading the logs of the device. When you select you device inside the edge settings, you will see another panel called Edge Logs. Open this to see the last 20 messages your device sent. These logs contain errors encountered during operaiton, as well as events that have triggered so you can monitor what the edge is doing with more accuracy

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/edge/troubleshooting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
