my computer is blocking an ip address

I resell web hosting services, have about 12 sites that I control. Recently the hosting company had a server issue and all sites were down temporarily. They are all back up now. The problem is there is one I can not see from my MacPro laptop OS 10.10.5. I can see that site from my iphone, from my husband's windows unit, from another Mac laptop and a desktop. But not from my main computer. This doesn't seem like it's a hosting company issue or a IPS issue, just my mac.

The hosting company suggested I do a pin and trace route, they say I have a 100% loss on these, so no data is going out. I have no idea why this would happen, or how to make that site appear again on my computer. Any ideas out there?

The site everyone else can see (but me) is www.4georgiabankruptcy.com.

Thanks for any help you can send my way.

Hello janburg,

Check your /etc/hosts file and see if you have a hard-coded entry for that domain.

Yes, the same result on 3 browsers, 2 of which I almost never use, so it's not browser specific.

I have a host.5 file, it's a locked file, and does not seem to have any IP addresses, just instructions.

Not sure what ups? Uninterruptable power supply? Sorry, I teach Tai Chi and do a wee bit of web work on the side, this one is beyond me.

Ok, but I think there's a bit more to it than that? I also typed in sudo dscacheutil -flushcache (which is on the etc/hosts file). Do I need to type something before adding the #?
