Hey,
i've done a a couple of fresh install of a medium size environment as outlined in reference architecture (lab and production pilot). Worked without issues.
Are you deploying small, medium size or large environment. If medium/large. Do you have the LB configured to only use the 1st node (the 2nd node is not added to LB until the installation is done)
Sorry can't offer more help other than: "worked for me". I used a SAN certificate
