Sudden connection issue on HTTPS sites.

[vile83er]

For some reason today, July 1 2016, every device on our home network is getting This Connection is Untrusted in Firefox or Your Connection Is Not Private in A Chrome when attempting to visit any secure site such as Youtube, Google, Paypal, etc.

This happening on 2 wired computers and 6 wireless devices (tablets and cellphones). All clocks are correct. My router ASUS RT AC68U has up to date firmware.

I just cant figure it out.

Well, I was able to fix it by manually adding the DNS to every connection in the house. I don't know why that worked but, it did.
