If you have a single machine that has chrome and some other browser (IE) on it, and the other browser is able to login fine, but chrome gets connection resets, I would suggest checking chromes browser settings.
From Okta, you can set blocked networks, but you would get a 401, not a connection reset, which really sounds like a networking or device issue.
I recommend opening a support ticket since information about you Org will be needed to help assist and see if the issue might be on the Okta side.
