However, it reports following error when clicking Publish in Project.( the account and password is confirmed many times, so mannual input mistake can be ruled out.)

I can see the ThingWorx Experience Server information in there.
However proxy information should be a proxy host that you use on your device to access the internet.
This is something that should affect you company-wide, not only on ThingWorx Studio.
