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:
