REST API call using system.net.httpClient

I'm making a GET API call to another server in our network that uses a self-signed cert for SSL. Ignition is generating a "unable to find a valid certification path" error. I have put the other server cert in the supplemental certificate folder, but that doesn't fix it. Two things I'm wondering if folks can help with with:

  1. Are self-signed certs just not usabled, and
  2. Is there a way for me to avoid cert validation in our dev/test environment?

Thanks,
Jason

This is how I'm doing it.

client = system.net.httpClient(redirect_policy="ALWAYS",bypass_cert_validation=True)
