I was tormented by this "resolving host" issue in both Chrome and Microsoft Edge for days!
This fixed it immediately and permanently.
Open Malwarebytes.
Click on the gear icon on the upper right (which is to the right of "My account" and to the left of the "?").
Under “Windows Explorer settings” turn off “Add Malwarebytes options to Windows Explorer”
Reboot your PC and the resolving host issue goes away immediately in both browsers!
Unfortunately this did not work for me. From time to time the resolving host issue would happen for both Edge and Chrome - rebooting would usually fix it but it's such an inconvenience. I've also tried some other solutions like disabling IPv6 but still it would not completely eliminate the problem. So far the only reliable solution for me is to uninstall MWB :(
Yeah, I was wondering why this isn't bigger news - maybe there aren't that many people out that that uses MWB? :(
