I have a T420 that I'm trying to make sure is up to date and it's stuck in the firmware update section on "Connecting to network share". I use the HTTPS section and leave the Downloads.Dell.Com in place and click next. It then warns me after a few minutes that "Lifecycle controller does not import HTTPS certificates at this time. Press 'yes' to continue". I hit yes and after a few seconds the activity bar freezes. I have left it sit there for up to half an hour with no signs of life. I have to hit Esc to back out and start over.

Now I already used the platform specific CD and updated some things, but I want to ensure everything is updated. The system has a valid IP address and has full network access.

Thanks in advance!
