I solved it by adding the following code to the "comfyui-reactor-node\install.py" file.

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

There could be a better way.

If it is a Windows system, you can try to configure the environment variable like this: set SSL_CERT_FILE=%APPDATA%\Python\Python39\site-packages\certifi\cacert.pem. The reason is that Python fails to locate the CA certificate.

can you explain more, i'm in the same issue, thanksss !

This problem has troubled me for too long. I checked all the required dependency version files and there were no problems, but the startup still reported this error

[Sethchen001]

如果是Windows系统，可以尝试这样配置环境变量：set SSL_CERT_FILE=%APPDATA%\Python\Python39\site-packages\certifi\cacert.pem。原因是Python无法找到CA证书。

The environment variables of this file have been set, but the same error is still displayed. Is there something wrong with the cacert.pem certificate file?

Where to find certifi's certificate:

Run the following command at the command prompt:

python -c "import certifi; print(certifi.where())" prints your certificate path

Finally set in the environment variable

After setting, restart and normal download will begin

I am running on MacOS Sequoia 15.1 and ran across the same problem.

What helped me was running this command:
open "/Applications/Python 3.x/Install Certificates.command"

Change the x to your python version
