[syslinux] hdt-project.org no IP?

[Michael D. Setzer II]

Unable to determine IP address from host name "www.hdt-project.org"

Getting this today? Not sure what issue is?
I paid for the renewal back in 08/04/2016 and and in 2015, so the domain 
should be current? But the whois seems to show it is expired? Went to the 
gandi site, and it doesn't show a renewal option or anything?
