Why can't I now not get on certain websites (I was able to get)?

[AC Question]

why cant I now not get certian websites (I was able to get)

I have a Samsung Tab A and a Samsung S5 phone, I can no longer get my own website on the Tab A But can get it via the S5 phone and on the computers (desktop is windows and lap top is apple) others are able to see it but when I do it goes to a different site to the one I'm after it seems to be stuck on the one (.com instead of .com.au). I can also get any other site I search for ??? strange any help would be appreciated.
