49. What do I do if my build upload responds with “Peer’s certificate issuer has been marked as not trusted by the user”?

curl performs SSL certificate verification by default, using a “bundle” of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn’t adequate, you can specify an alternate file using the –cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you’d like to turn off curl’s verification of the certificate, use the -k (or –insecure) option.

50. If your project is already registered in Scan, how do I get an account?

If your project is already a Registered Project in Scan, but you are not yet a registered user of Scan, you can register with Scan, and upon registration, you can click on Add Project, find your Registered Project in the project table, and request access to the Registered Project of your choice. You will be granted access subject to approval by the Registered Project owner or Scan administrator.
