I have a 2012 Leaf as well. That sound at the end of your video is very familiar. I'd guess it's a motor pumping coolant around the charger fluid circuit.

I actually wanted to remove the potting material and what you see is probably the damage from that attempt. But I also checked the resistor and to my surprise, it shows open. [It either was damaged before or maybe my knife has cut it].
My resistor measures about 317k Ohms.
The black potting in the fenced areas is easy to remove with a wooden spudger stick.
i use a bamboo chop stick that has one end sharpened to a point and the other end whittled to a flat blade like a screwdriver, it is easy to pry the material out with wooden tools to avoid damage from knives and metal tools.

The first click is from the connector, then i dont move it anymore. The sounds come from somewhere behind the motor, the first two clicks and the blue lights flicking are as usual when connecting the car for charging, but then they click again and the light turns off, and the whole cycle starts again with clicking. Now that you mention it does sound like relays.
And no, i cant charge at home since a couple of weeks with the j1772 which is the real problem here. What i meant is i cant use any of the free charging poles in our city, i started noticing about two years ago that the newer ones did not work with my car anymore, literally nothing happens when i connect. no lights, no clicks, nothing. my hypothesis was that they maybe are too strong (7 kw +) or "speak another language", but in retrospect maybe there was something faulty with the on board charger already?
I am a fairly competent home mechanic, but electronics are not really something i understand and i am struggling to find the fault. I would really appreciate any help in figuring out where the problem is, i can then change parts and so. Do you guys think my problem is with the on board charger?
I borrowed a j1772 from a friend with a 2016 model to check if my j1722 is the problem , and the car makes the same sounds and does not charge. i also checked the plug connector in the car and the cables from it to a box behind the motor, and the cables and connector were all good.
You may have an issue in the OBC, but to be sure and know where to look it would help to find out which DTCs have been thrown and stored. The issue could be in the communication with the EVSE, or within the OBC; The codes would help determine where to look. A dealer could read the tools with the Consult scanner tool, or you can do it yourself.
An OBDII reader such as the scantool OBDLink LX has bluetooth to connect with an android device running the leafspy app, and it will display the codes from all the ECUs.
There is a good thread discussing the diode issue with a successful repair,...

If you conclude that you need an OBC, there seems to be a rather expensive OBC in Norway: https://finndel.no/delinfo.aspx?f=750&dnr=23931... I think the prices approaching to the levels to consider conversion to 3 phase aftermarket chargers.
In case this wasn't already asked: do you have a charge timer set?
