Establishing a connection to an SCP server
When you try to access an SCP server, the device must use the server's host public key to authenticate the server. If the server's host public key is not configured on the device, the device will notify you to confirm whether to continue with the access.
If you choose to continue, the device accesses the server and downloads the server's host public key.
If you choose to not continue, the connection cannot be established.
As a best practice, configure the server's host public key on the device in an insecure network.
