Sometimes we see the agent connect to the LimaCharlie cloud, enrolls, then disconnects (which is normal the first time after enrollment) and never connects again, or it doesn't show that kernel has been acquired.

This behavior is typical with SSL interception. Sometimes it's a network device, but at other times some security products on the host can do that without being very obvious.

You can confirm if there is SSL interception by performing the following steps to check the SSL fingerprint of the LimaCharlie cloud from the host.

Confirm the region of your organization

If you already know where your organization's region is located, you can move to the next step. To verify the organization's region where the data is processed and stored, click Add Sensor from the Sensors view.

You will then see the region listed under Sensor Connectivity.

Open the test URL

Via web browser, navigate to one of the below test URLs that corresponds to the correct region:

No website will open; you should get a "Your connection is not private" type of message instead.

Display the SSL Certificate

By clicking near the URL bar on the exclamation mark, you will open a small menu and you can click something like "Certificate status"/"Certificate validity"/"Certificate is not valid" which will display the certificate information.

Confirm the SHA-1 and SHA-256 fingerprints

The SHA-1 and SHA-256 fingerprints should match the values below that correspond to the region your organization is in.

If the SHA-1 and SHA-256 fingerprints you are seeing do not match what's listed below, that's an indicator of the SSL interception.
