This will take you to the following screen shown below, and when you reach this tab, you will then need to click change adapter settings.
The next screen you will see after clicking change adapter settings will be the one shown below. In this windows tab, you will see all current network adapters your PC has access to.
Right-click your current network adapter and hit Properties at the bottom of the Properties tab shown below.
Doing so will reveal a large tab with a lot of settings shown above. Don't worry about all of those settings, as all you need to do is find and uncheck Internet Protocol Version 6 (TCP/IPv6).
After unchecking Internet Protocol Version 6, confirm the changes by clicking OK and restart New World if you haven't already. When you log back in, the mm_connerr_rep_timeout error will hopefully be fixed.
But, If the problem doesn't disappear, we recommend restarting your PC, flushing DNS, and restarting your router, as alternative fixes.
