解决：CondaHTTPError: HTTP 000 CONNECTION FAILED for url

利用miniconda安装python3.9的环境时，报错如下：

本地可以打开报错的网站，即 https://repo.anaconda.com/pkgs/main/win-64/current_repodata.jsonchttps://repo.anaconda.com/pkgs/main/win-64/current_repodata.json

尝试了各种方法， 包括，

1.【不能解决】更换清华源。 参考：【conda】解决 An HTTP error occurred when trying to retrieve this URL.问题 – CodeAntenna

# 重置源配置
conda config --remove-key channels 
# 重新添加清华源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/ 
conda config --set show_channel_urls yes

 2. 【不能解决】设置ssl_verify = false

3. 【解决】将如下两个dll文件copy到C:\Users\%YourUser%\Miniconda3\DLLs

C:\Users\meiranp\Miniconda3\Library\bin\libcrypto-1_1-x64.dll

C:\Users\meiranp\Miniconda3\Library\bin\libssl-1_1-x64.dll
