Rstudio on Windows not working with github copilot

We are trying to get Github copilot working with RStudio on Windows 11 desktop and we are failing on the ghost text. We are getting this message in the detailed log:
RESPONSE

{"jsonrpc":"2.0","method":"LogMessage","params":{"level":3,"message":"[ERROR] [ghostText] [2025-04-24T18:25:18.378Z] Error on ghost text request: (FetchError) The pending stream has been canceled (caused by: unable to get local issuer certificate)","metadataStr":"[ERROR] [ghostText] [2025-04-24T18:25:18.378Z]","extra":["Error on ghost text request: (FetchError) The pending stream has been canceled (caused by: unable to get local issuer certificate)"]}}

Note that VScode running R on the same workstation works fine so this is related to getting RStudio to recognize the certificates.
I have found several other issues related to this error and they end up setting environment variables pointing to a certificate bundle. We have tried those with no success.
Is there an environment variable specific to github?
What else can we try ?
This is working on linux and ubuntu servers, it is only the windows desktop with the certificate errors.

Thank you
