So it appears that when setting HTTP_PROXY and HTTPS_PROXY as environment variables fetching the certificate works, but timestampinf fails. If I remove the timestamp then the singing is completed without issues.

Additionally when I set the proxy via windows GUI (Proxy Settings) control panel then it also works.

Anyone know why this does not work when setting the HTTP_PROXY and HTTPS_PROXY settings as environment variables?
