It is recommended that you check the status of MSN before you made any changes on your systems:-

Go to: http://messenger.msn.com/Status.aspx



If the page displays "Service Unavailable", this means that the problem comes from the Microsoft servers!


Then uncheck the box "I use a proxy server."
Reconnect if necessary.

Make sure that Internet Explorer supports the standard 128-bit encryption:
Open Internet Explorer
Click on "Help"
About Internet Explorer


If it is less than 128 bits, download and install Internet Explorer with a higher encryption level.

For identification, MSN Messenger needs encryption

In Internet Explorer:
Click on "Tools" >Internet Options >> "LAN Settings"


In the "Connection":
Check the box "automatically detect ..."
Click OK.


If that does not work, try:
Check if a proxy has not been activated:

MSN:
Click on Tools >Options >Login
Click on "Advanced Settings"


Verify that the "HTTP Proxy" - "Server" is empty.
If it contains an address, delete it (it was probably the address of a router).

The problem may be a version of MSN unofficial. If none of the works, uninstall the version of MSN installed and download the latest version
