Hello! I have same problem. i can Update when i connect to my university VPN. but i can't update with my local internet connection. the strange thing is that i have access to update.eset.com (i successfully ping it). it means that while downloading update, i disconnect from VPN and download doesn't stop. the problem is in first step (only in checking for update). changing update type doesn't solve problem and still checking section have problem.
i install the latest version and i didn't update from v9.
i have attached the update log
thanks!
