Cant use live link

I have been using local for about 2 years now. It has worked fine with tunneling on numerous occasions. It’s just intermittent issues depending on which site I view and this was the last straw. If cant be user or security permissions when it works on one site and not another. How could it update hosts file for one site and not another? Is security a minute by minute proposition? One minute it is allowed, the next minute it is not? Doesn’t sound logical to me.
