Can't access Dropbox via both Chrome and Safari, and can't sync my document with the dropbox client

After I back from china, my dropbox client didn't work any more in my macbook. What's more, I can't access the website of facebook, twitter, and dropbox in Chrome. I keeps getting the error showing in the image below.

Then I tried with Safari, what suprising is, facebook and twitter can be successfully accessed, but dropbox still not. I tried to clean cache of my Chrome, tried OpenDNS, tried to clean DNS data of my laptop. All of them didn't work. But Youtube still works fine.

I tried to ping all the above mentioned website, the results are all "requst times out". I don't know what happened, can any one hel me out?

MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.5)

Hello Lavinia Chen,

Welcome to the Apple Support Communities!

I understand that after returning from China, you are able to access Facebook, Twitter, and YouTube in Safari, but not the Dropbox website. To begin troubleshooting this situation in Safari, I would suggest reading over and working through the suggested steps located in the attached article below.

I tried to troubleshoot the problem, but is doesn't work😢

I mentioned before, that I can't successfully ping Dropbox, Facebook and Twitter website. So I think maybe the problem is in network setting. But I have no idea what happened.

Do you have any idea what is wrong? Thank you very much in advance!

Dear Eric,

Thank you! The problem has been solved.

I think the problem is that, my hosts filed was malicious tampered by the GFW system!!! I reset my hosts file to default, then everything is fine now!!! Thank you for your help!

Cheers
