Router says contact your ISP about DHCP not functioning properly

I am having a similar issue to this thread: https://forums.xfinity.com/t5/Your-Home-Network/Your-ISP-s-DHCP-is-not-functioning-properly-ASUS-router/td-p/3331178

We had a major outage a few weeks ago and have been having the problem since then.  I actually have two different routers to try and get the issue with both.
