This could happen because of following reasons:
- Is your Classcloud connected to Internet? If Yes, then
- Are you following the proper Steps for Data Sync?
- If you are getting "connection error" message please check the internet by visiting other websites like google.com,yahoo.com,youtube.com
- If you cannot access these websites means currently internet is not available.
- You can try after some time once the internet is back.
If internet is available and you are still not able to do data sync please connect with our customer support team at firstname.lastname@example.org
