I found the issue - a pesky little slash! I found it referenced by brownj in Nov 2019.
Restore location needs to be ‘/home/user-data’ NOT ‘home/user-data’.
(I was missing the preceding ‘/’)
It is also helpful to remove the ssl cert on the new install.
rm -rf /home/user-data/ssl/*
THEN re-run the MIAB installer.
I’ll move the dns/glue records later tonight.
