If instaled, try temporarily disabling anti virus software.
If you don't have a/v software installed, try a different DNS server.
Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.
Enter these addresses exactly as you see them here.
Then click OK.

I forgot that I had a program called "Rapport" running that I had downloaded months ago with no problems since.
I disabled Rapport and my problem seems to have been resolved. I then re-enabled Rapport and so far the trouble has not returned. I am thinking that maybe it updated itself automatically and that update caused issues until it was stopped and then restarted.
Thank you so much for your help, I really appreciate it.
