Issue 1021 on fresh install

Technical Support
1

Hello,

I recently purchased a new laptop and did a fresh windows install on another. After doing all windows updates and downloading the game, both computers can not log into the game. It hangs at “Connecting to Blizzard server” and eventually gives error code 1021. I have done the recommended steps with my router (kept it unplugged completely for 4 hours) and still have the issue.

As a side note, I have an older PC that I hadn’t used in a while and it is able to load the game just fine.

So the issue is only on the 2 laptops that did a fresh Windows and Diablo install.

Any suggestions?

Here is my DxDiag , the full one is too big to post. I also noticed I have the same error in SC2:

Hey, cybrwlf! Thanks for including details here. I’m not too concerned with what we have on the DxDiag, though incomplete. There was common language runtime error and radar preleaks, but it typically shouldn’t cause this behavior.

The 1021 error is typically tied to a connection issue and with this happening with 2 of the 3 devices on the home network here, it sounds a bit like there may be a common connection or network issue.

Could you try an alternative connection to see if this works for one of the laptops? While not supported, a VPN is another option. While this won’t eliminate the home network as a concern, it should reroute the connection and change the DNS.

If either helps or neither can be done, trying another DNS provider like Google DNS or Cloudflare may be some alternatives to try.

If it persists, let’s gather a WinMTR test while attempting to connect for 5 to 10 minutes. Copy and paste the text file created and paste it between two ~~~ like so:
