Many disconnects during a game

Hi all,
As I play the game I get several disconnects where everything stops and then fast forwards to the point where the game continues. I’ve noticed that it happens every-like objectives or like people throwing new spells once a while which render the game unplayable for me.
I love the game and the characters but I can’t be a worthy champion amidst the fight as I disconnect almost always at the neck the time.

I’ve looked at the game logs the only notice I could get is this:

NGDP Name Resolution Failed: ^https://level3.ssl.blizzard.com/^
NGDP Downloader Error: DOWNLOAD_ERR_NAME_RESOLUTION_FAILED
I dont really understand the error and I dont really know if this is the error causing this issue.

Here’s what I tried:
1- reset network.
2- use different internet.
3- reinstall game.
4- use different pc apparently my brother and I dc at the same time.
5- use different DNS.
6- delete temp heroes of the storm folders.
7- repair the game.
8- use vpn.
9- replaced old HDD with SSD hard-drive.
10- used 3rd party programs to regulate internet like a trial of Wtfast.
11- reduced sound quality and graphics to minimum.

PLEASE HELP I’m really frustrated and I can’t play with my friends this way.

Thanks all in advance.
