Original GitHub issue: https://github.com/Comfy-Org/ComfyUI-Manager/issues/998

Good day! When I try to install any upscaler via "Model manager" button, I get the following message:
Install model 'ESRGAN x4' into 'C:\ComfyUI_windows_portable\ComfyUI\models\upscale_models\ESRGAN_4x.pth'
[ERROR] <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)>

Could you help, please?
