Right so "checking" the hosts file doesn't do anything. Here is the idea: In the hosts file add an entry for qrz. As I said you likely can't edit the hosts file where it is. Copy it, add the following, save it then copy your modified file back to the original location. Win7 and win10 are rude about folder permissions and the copy back will generate a warning but it will still copy. Verify your copy is the file in the original location when you are done. BTW - site cannot be reached is NOT the same as a site cannot be found error message. "Cannot be reached" sounds more like a routing issue than a DNS issue. # Modified hosts file # Add qrz IP address here if they change later you will have to fix this 18.104.22.168 qrz.com 22.214.171.124 xlmdata.qrz.com # This should eliminate any sort of DNS issue on your end.
