Pidgin + The certificate for omega.contacts.msn.com could not be validated

If in pidgin you get a error
The certificate for omega.contacts.msn.com could not be validated. The certificate chain presented is invalid
On connection with msn…..

My guess is the old certificate in pidgins folder is outdated

This is what I did to fix it

cd $HOME/.purple/certificates/x509/tls_peers
rm omega.contacts.msn.com ows.messenger.msn.com rsi.hotmail.com
wget http://files.andreineculau.com/projects/pidgin/omega.contacts.msn.com.txt
mv omega.contacts.msn.com.txt omega.contacts.msn.com

Restart Pidgin and you should be good to go

NOTE: Can be fixed by deleting certificate from Pidgin menu Tools/Certificate.

Solution
a. open https://omega.contacts.msn.com/
b. On the URL bar, click on the security lock (usually just in front of the URL). Click on the certificate information.
c. Go to the Detail tab and click the “Export” button. Save the file as “omega.contacts.msn.com” (without the quotes).
d. Copy and paste this file to $HOME/.purple/certificates/x509/tls_peers
