Just a heads up to all out there who are using either DSL/Cable (anything that is dynamically assigned by the ISP), if you happen to be in the middle of something on your machine and it happens to catch the modem/router in a cycle (meaning its renewing the IP or its rebooting, happens all the time) then you will temporarily have packets that have (without getting into too technical of a packet structure discussion) mismatching header/frame/source/dest ip addressees as well as IP CEF or local DNS cache mismatch causing ABE to trigger as a local block. That is NORMAL. Specially on Windows machine where in the absence of a valid IP/WAN connection, it creates and assigns virtual addressing which is indeed YOUR OWN MACHINE, hence, LOCAL.
Normally easiest and QUICKEST fix, wait until the cycle is complete, close your browser and try again and all is well in the world. If not an option, can't see why, then just open the link you were working on in a new tab and that should do it. Or all else fails, force a DNS update inside the browser, toggle the option and that should force a clean up for any cached entries. This information has come from lots of personal and observational experience. Hope it helps.
