Error code 1522 typically means your device isn’t connecting to the activation server, which is required to activate your Stellar software. This can be caused by a weak or disrupted internet connection on your end, or a temporary issue with the server itself.
To fix this issue, start by checking your internet speed and confirming that your connection is stable and active. After that, wait a bit and try activating the software again.
If the problem persists, it may be due to a temporary disruption with the activation server. In that case, feel free to reach out to our customer support team— please email support@ontrack.com.
