AT&T Gateway Blocking Access to Regions Bank

I have been mystified by my problem for about 6 months now.  A previously functioning app I use for my person finances, moneydance, will no longer connect to my bank, Regions.  At first it was intermittent but in the last month or so it has become permanent.  I find that when the app won't access the bank, it so happens that even my web browser won't access the website for regions.com.  After much ado and attempts to resolve through the bank and through AT&T support, the bank denied any association with the issue and said it was an ISP issue.  AT&T attempted a check of my system and could not find a problem. 

I continued to research on my own and tried a proxy server to access the bank, successfully.  So that pinpoints the issue to AT&T gateway not allowing access to the bank.  I need help getting this block removed!  I am copying the text from my command prompt window in which I did a ping to the regions.com site and I also did a tracert.  Please refer to the following for evidence that it times out:
