Re: Error 104: The attempt to connect to the server failed.
Think so this error is coming to some incorrect firewalls settings. The windows firewall or other virus protection software or application will be having the settings which does not allows any other browsers accept Internet Explorer to use internet.The antivirus or a firewall application is blocking access to port 80 (the port used by web servers to send you pages) by Google Chrome or Firefox. So, i would suggest you to turn off the firewalls or any firewalls application there on your machine and check weather same error is coming back or not. Think so it error will not come back.
