Have a problem with open Premiere Pro

Hello, everyone, I need some help. I installed a program Premier Pro, but I can't open it. What it tells me is:

Unable to check the status of your subscription.

Cannot connect to Adobe servers. You may not have an Internet connection. Check your connection and try again. If the problem persists, see the troubleshooting guide. Error code: 12015.

I was subscribed to Premier Pro, then canceled for a period, then I'm back to subscribing again and now the program is not responding. My internet is fine. Tried to troubleshoot the problem as advised in the link, but no result. Maybe someone can suggest a solution to the problem?
