I setup a RPI3 with Raspian about a month ago. I installed Apache2 with PHP7. I created a webpage that simply has the date and time on it to start. I setup a couple of Android tablets to show this page in a couple of rooms for the house. All was working well. I go on vactationa and there is a coule of power hiccups and all of the sudden the page won't load on tablets, or at least it will work on my laptop, and my android phone, the other devices say the page is unreachable. Even the PHP info page I have there is unreachable. I rebooted the Pi with the same result. Anyone have an idea what might be going on? I have no firewall at all on the Pi.
