The reason for asking about breed is because I think you might be really familiar with it. I’m just a curious hobbyist and have no other motivations. I just volunteered to do some testing for someone that is trying to do kernel improvements for the MT7621.
My reason for asking about TSL/SSL is bc if my browser has the HTTPS-Everywhere addon installed it mixes up the pcWRT blocked site filter warning. Sometimes it is unclear if the website is down, is a http site but blocked by pcWRT, or is just blocked by pcWRT.
