this is a temp ban correct? if so how long will it last

Yes and there is no way to tell. Anywhere from a few minutes to a few days.

ok thanks for the help

It can last anywhere from 5 minutes to 72 hours to be exact. The more you attempt to try it the longer it will take so just take a day off and just try again in the morning, most are 12 hour ones.

It takes 60 seconds if you reset your router ( only if your IP is changeable)

i usually check again in 5 minutes, if that doesnt work, wait an hour and try again

if it doesn't work in an hour, try again in 6 more hours.

After 6 hours doesn't work, try again every 6-12 hours.

anywhere from 2 minutes to 12 hours

There's a few guides that can help u bypass it, if u have a Dynamic IP address... Sorry I can't link from my phone

As a side note: failed login attemps will not increase the time as per Blizzard supports Temp Restriction explination

Links for guides & temp rest explination can be found in my profile since I can't link them from my phone
