All of a sudden I am getting UNABLE_TO_VERIFY_LEAF_SIGNATURE error when I use the HTTP node with an HTTPS request. I can see that this was an issue back in 2014, 2016 so I am puzzled why I am seeing this issue right now.
The site I am trying to access looks OK in Chrome. And I have not made any changes to the flow, or node red. It was working OK.
Yesterday there was a power outage and the PI rebooted, but that is all.
