Bing will not open as home page after Build 10565 upgrade

Have run into a wired issue, and I'm not quite sure why. After upgrading to Windows insider build 10565 I am not able to open bing.com as my homepage in either Edge or Internet explorer 11. I can open any other page without issue, but not Bing. If I set google as my home page...WALA.. first time every time, no problem, set it back to Bing...Can not find requested page pops in after about 30 seconds of trying to connect. Have cleared cache, run DISM diagnostics, nothing reports as an issue. If I set Bing as a Favorite in the favorites bar, open to google as my home page then click the link, it opens without issue, but when set as the home page...nada.

Anyone seen or heard of this issue, or have any ideas how to correct it.

Thanks,

Update:

Now it won't open from the favorites link either, same message:
This page can’t be displayed

• Make sure the web address Bing is correct.
• Look for the page with your search engine.
• Refresh the page in a few minutes.

Really annoying

Resolved the issue. Was external DNS. Was having issues with my ISP DNS (AT&T) about 4 days ago so I decided to switch my external DNS to point to Googles DNS servers, well that was the issue at least on my primary system, This morning I switched the external DNS back to my ISP and bingo...Bing again, first time every time.

Not sure why this was the case with Google's DNS servers, never had an issue with them before, unless there was a conflict with the AT&T gateway and the DNS servers, but as long as it's fixed that's good enough for me.
