Hi William,
For your information, my colleagues can login now.
The above situation applies to IE Browser, 360 Browser, and Chrome as well.
We have about 10 client computers in our office, not in a network environment. No firewall behind just a normal broadband and router setup. We had two computers acting up with that situation. As I mentioned above, I tried resetting all three browsers, flushed
the DNS etc.. None of them work on that day. However, the next day, it was back normal and can access the login page. Please note that one of the troubled computer has not changed anything. No resetting in browsers and flushing of the DNS. We did not reboot
the router as well.
If you ask my opinion, I have a feeling is the DNS routing in one of MSFT. As you can see in the tracert I provided above.
regards,
Roger
