# Troubleshooting data sources

****My connected data source shows an "AUTHENTICATION_FAILED" error****

🤔 **Problem**

If your data source was ingesting data correctly, and suddenly stopped with an “AUTHENTICATION_FAILED” error, you might have to refresh your credentials.

🌱 **Solution**

Some data sources, like Azure, generate credentials or tokens for a limited amount of time that need to be periodically refreshed.

1. Open [Hunters documentation](https://docs.hunters.ai/).
2. Search for the required data source and read the integration instructions.
3. Perform the required steps to create or renew the credentials on the data source side.
4. Open the Hunters portal and click on the 3 dots on the right side of the data source.

5. Edit the credentials and test the connection.
6. After the connection test is successful, click Apply.

If the issue persists, open a ticket to Hunters production services via the support portal.

****My connected data source shows an "ACCESS DENIED" error****

🤔 **Problem**

If you’re trying to connect a data source through an S3 bucket and you’re receiving an ACCESS DENIED error, it could be due to incorrect bucket settings.

🌱 **Solution**

1. Open the relevant bucket on AWS.
2. Open the bucket’s **Permissions** tab and scroll down to the **Object Ownership** section.
3. Click **Edit** and change the policy to **ACLs disabled**.

If the issue persists, open a ticket to Hunters production services via the support portal.

****The Apply button is disabled on a connected data source****

🤔 **Problem**

You opened a data source that is already connected and the **Apply** button is greyed out. When you hover over it, it says "Nothing has been changed". Clicking **Test Connection** does not enable it.

🌱 **Solution**

This is expected. **Apply** saves changes, so it stays disabled until you change something. **Test Connection** only checks that Hunters can connect with the details in the form; it does not save anything.

Make the change you need: edit a field (for example, enter new credentials), select or clear a data type, or turn the integration on or off.

Click **Test Connection**. Until the test has run, hovering over **Apply** shows "Test connection before applying the changes". The test is not needed when you are turning the integration off.

Click **Apply**.

To discard your edits instead, click **Reset**. If you only wanted to check that the connection works, run **Test Connection** and leave the page; there is nothing to apply.

If the issue persists, open a ticket to Hunters production services via the support portal.
