Authentication failed.

I haven't used HB in a while and wanted to start again but when I enter my key it says "authentication failed".

 

are you sure the key your trying to use is the same one listed on the buddyauth website? are you sure theres no spaces before or after your key?




if your sure, try flushing your dns

reset your host file back to default.

and try power cycling your home router.

 

I tried all of these things and it still says authentication failed

 

ok got it to work I had to disabled my nat loopback
