I have SharePoint Online site that contains Document Library with Word document, below are the errors messages when I try to open the word documents using the broswer

IE Error This page can’t be displayed
•Make sure the web address https://euc-word-edit.officeapps.live.com is correct. •Look for the page with your search engine. •Refresh the page in a few minutes.
on Fiddler I get this error
[Fiddler] The connection to 'euc-word-edit.officeapps.live.com' failed.
Error: TimedOut (0x274c).
System.Net.Sockets.SocketException A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
What is blocking the connection, could it be firewall?
