Iffy plugin – sometimes works, other times blocks random countries

We are in 2 countries, U.S. and Spain. Randomly we and site visitors from these countries will be blocked, but then the site will be accessible a minute later. Can’t have this.

Also, you have to add all other countries manually to the list – there is not a “check all” and them remove what you want in the list.

Too many random blocks to rely on.
