website not working only on my home network

[akidinspace]

I regularly visit a website (www.chatzy.com) but when I tried to go there yesterday it wouldn't let me connect, it would just give me an error ( ERR_NAME_RESOLUTION_FAILED) I thought it was down so I waited till today to see if it was up, but it still doesn't work. I checked on one of the "is it up?" websites and the site is indeed up, I just can't access it and get the same error every time. it's not the device, I tried on 2 separate laptops and my phone with no avail. but the thing is, if I connect to the website through my mobile network, whether it be directly on my phone or running a hotspot for my laptop, it works fine. it also works if I use a proxy such as hidemyass when on my network. any ideas on how to fix this? network provider is centurylink/cox btw.

also, I have already tried resetting my router and checking my router settings to make sure it's not blocked.

sounds like a dns or blocking issue on the isp side.. see if you can get the ip address of the site and connect to it using that.
do you have any friends who live locally on the same isp who can try?

Also can't access a website ( http://pcdiga.com ) since some days ago, just like you, but the error is different: https://scontent-a-mad.xx.fbcdn.net/hphotos-xpa1/t1.0-9/10357521_694038720668950_1275099637155414321_n.jpg (just the IE11 example on my gaming PC, tried Chrome 36 and another PC, iPad Air and iPhone 6).
I did write quite a big topic on this forum yesterday about it, included all of my findings and things I tried to do, but within 5 minutes it simply vanished so I got EXTREMELY pissed for the huge waste of time writing it, now I just get a 404 on it. Here's the linked I saved from it: http://www.tomshardware.co.uk/answers/id-2230076/connect-website-internet-connection.html

So, I really hope someone knows what's up and can provide a solution to both of us!
(things I've tried to do so far include clearing the DNS, use OpenDNS, add pcdiga.com to allowed lists, disable router and PC firewalls, etc.)
