Web communication requires certificates to ensure safe data transfer. Even though Parametric Robot Control runs primarily in a local context, gRPC requires encryption to function.
In order to trust the certificate embedded in the server (PRCServerCertificate.pfx for Windows with a validity of 30 years, PRCServerCertificate_macOS.pfx for macOS with a maximum of 2 years validity) a root certificate needs to be present on every client.
<aside> 🔑
Note that the most recent version of Parametric Robot Control provides a certificate that not only works on 127.0.0.1 and localhost, but also on the following IP addresses:
192.168.0.110 192.168.0.110 192.168.8.110 10.0.0.110 10.0.1.110 10.0.8.110 172.31.0.110 172.31.1.110 172.31.8.110
There should be ways to integrate your own certificates as well, contact us if you need support.

The PRCRootCertificate.crt certificate is by default installed by the installation software on Windows. You can also find it in the server directory, in Windows by default %LOCALAPPDATA%\Parametric Robot Control\PRC.Server\Certificates. To install it automatically, you can run the PRC.CertificateInstaller.exe file (the same file is also run after setup).
In the PRC.GH folder, open the Certificates subfolder in a Terminal in that folder and enter the following command to install the certificate.
security add-trusted-cert -r trustRoot -k ~/Library/Keychains/login.keychain-db ./PRCRootCertificate.crt
The same command is also available by double-clicking the CertificateInstaller_macOS.command file in the Certificates directory in the PRC.Server directory. However, your mac may prevent you from executing that command. You can simply open a Terminal window and enter bash CertificateInstaller_macOS.command
Go into the %LOCALAPPDATA%\Parametric Robot Control\PRC.Server\Certificates folder. Double-click the PRCRootCertificate.crt file, select "Install Certificate" for "Current User". Then select "Place all certificates in the following store" and choose "Trusted Root Certification Authorities".
