I’ve uploaded the anking deck today from google drive, it has a volume of 3 GB but the sync wouldn’t be made and it’s showing me this message 
i don’t know what to do so i can fix this problem
By the error message (“dns error … os error 11001”) and a bit of googling, it looks like something was wrong with your internet connection. If you’re using VPN, try to disable it.
But are you sure if failed? Could you scroll down to the last line? Could you log in into your AnkiWeb account with your web browser and check its disk usage?

Since it’s a duplicate, I’ve replied to it in the previous post.
