Turns out i had more than just the usual dirt and debris because it wouldn't charge again, so time to investigate. i have a Blink WE-30 level 2 EVSE unit that is mounted outside under a shade tree.
First obstacle is the security screws on the EVSE handle, and they are not 6 pt torx either, they are called Torx Plus Security screws with 5 splines and a center pin. These are called size TPS15. $25 bucks for a set of bits if you can find them. They were repaced with regular #6 x 1/2" wood screws philips head

Then i found bugs in the hardware--alabama fire ants crawled thru the 3 little vent/drain holes in the handle and made a nest.

Not much stuff in the handle, just a pocket full of shells. Not surprised to find this handle was made in Germany--silver label under the circuit board, the mains line wiring colors, and the use of those stupid TPS screws were the clues:

Gave it a good cleaning, and now it's charging again. So check for bugs, they are not always just in software...
