countering the London


You should post a game you lost in the London. I checked a few games in your history, but only one game had something similar to the London. In that game, it seems like you went after the wrong pawn and your opponent was able to queen another pawn. This wouldn't relate to the London though. It's more of endgame play you would need to work on.
So, if you have a London game you lost, then post it.

Have you seen this youtube video? ย The second line he shows looks interesting. I may give that one a try myself.
Agadmator also has a yt video that looks pretty good.

I wrote an article about the exact problem last week and how you can improve. Might wanna have a look: https://www.chess.com/blog/SharpCube/why-you-lose-against-the-london

the following contains links to resources for playing the London System as White, or against it as Black...

There is no way to "counter"ย the London system. If there was, it would disappear from high level play.
You should just concentrate on playing good chess without many mistakes. Any game that you lose is certainly not because of that opening, but because of blunders.
That said, I struggle to find even a single game in your past that featured the London. Maybe you should link one.
