Unable to establish SSL connection

When I try to run python examples/show_battle_game.py on my Win10 WSL, I got the following error:

Download data/battle_model.tar.gz from https://raw.githubusercontent.com/merrymercy/merrymercy.github.io/master/_data/magent/battle_model.tar.gz... --2021-01-17 20:46:33-- https://raw.githubusercontent.com/merrymercy/merrymercy.github.io/master/_data/magent/battle_model.tar.gz Resolving raw.githubusercontent.com (raw.githubusercontent.com)... 151.101.76.133 Connecting to raw.githubusercontent.com (raw.githubusercontent.com)|151.101.76.133|:443... connected. Unable to establish SSL connection. ERROR: wget fails! If you are an OSX user, you can install wget by 'brew install wget' and retry.

It seems to be able to connect to raw.githubusercontent.com, but I can not understand why it says Unable to establish SSL connection?
