I have encountered this. An earlier thread said Bitdefender had fixed in several months ago.
Same problem here. Just today.
Not that I wish this on anyone, but something in my upbringing makes me think it's my fault.
I am getting the same error.
It seems to be an intermittent problem - I changed to using another connection and it was OK.
Hello!
It was a temporary error and it has been fixed right away. Sorry for any inconvenience.
