After the Jan 18 windows10 update, I had to re-install ACP and re-enter the ACP license. I have verified that local lan access via web brower to the lan IP is working just fine but remote access via No-IP address is not working. It just reports that address not found.

I thought there might be something wrong with no-IP DUC program.. Found that there was a new version 4.1.1. Downloaded it and updated software from 3.1.1, The ClientID, update and IP addresses on the No-IP status display all appear OK with check marks. There are 0 notices and 0 alerts on No-IP interface. Trying the site hostname with the Web Server Internet enabled as usual in ACP is not having any connection with ACP web interface.

Do not know where to proceed next with resolving the problem.
