several seconds ? looks like you've got a timeout problem on name
resolution (or another network access). Please ensure that DNS or name
resolution traffic is not blocked.
More over, add a rule to accept loopback traffic on INPUT, blocked
loopback traffic could explain problem you have.
Hope this help,
