flash installer for mac is asking for proxy credentials for adobe.trackers.snd.com

Flash installer for mac is asking for proxy credentials for adobe.trackers.snxd.com port 80 realm:  Multiple_User.  If I click continue, installer fails.  I do not have a proxy server on my home network and I have never been asked for credentials before.  Not sure if it is related or not, but I did delete some expired certificates in my keychain and I do not know if adobe was one of the certs.  Does anyone know how to fix this?
