(Error code 022fe2)
This error originated from one of the following locations within the iPXE source code:
DEBUG=ocsp(Please edit this page to include any of your own useful hints and tips for fixing this error.)
An OCSP server somewhere in your certificate chain is broken.
Maybe the OCSP server might not know about the cert yet if it is very new.
By building iPXE with DEBUG=ocsp you can see the offending certificate IDs.
