I am having the same trouble
I am trying to use O2's free web based text messaging service. When I log into the O2 site at
http://www.o2.co.uk/home and select to send a free text message it redirects to
http://sendtxt.o2.co.uk/sendtxt/and returns an error message.
I have tried both Firefox and IE browsers and get the following error messages:
Firefox error message
Failed to Connect
The connection was refused when attempting to contact sendtxt.o2.co.uk.
Internet Explorer Message
Internet Explorer cannot display the webpage
i have tried adding
http://*.o2.co.uk to the trusted sites in IE but still does not load the page.
Can anyone advise us please
