Solving certificate validation errors on browser while navigating on RC web pages

How to solve certificate validation errors on the browser while navigating on RC web pages?
If your browser displays a certificate validation error when navigating to RC pages, there could be two causes:
  • the remote host's certificate has expired
  • you are using a Private Root CA
If you are using a Private Root CA, the certificates in the Private Root CA chain must be added to the Operating System's Trusted Root Certification Authorities. For more details, consult your operating system's specific manuals. Remember to close and reopen your browser after adding certificates.
