Cannot verify sas.goog certificate

[ironshi]

I am currently trying to register SAS with CBSD, but whenever I access https://sas.goog/v1.2/, I always receive

ERROR: cannot verify sas.goog's certificate, issued by ‘CN=WInnForum RSA SAS Provider CA,OU=RSA SAS Provider CA 0002,O=Insta,C=FI’:

Obviously, there is no CA Certificate for sas.goog in my machine.
Where can I obtain the CA Certificate for sas.goog?

In general, CBSDs are able to connect to the SAS out of the box. If your CBSD is experiencing certificate errors, we usually recommend reaching out to the CBSD vendor for assistance.
