Check Ability To Resolve Domain Names

On the machine that runs the service run below command:
nslookup my.patientsknowbest.comThe command will query a name server for our address. Which name server is picked depends on the confguration of your system/network.
TIP: Run:
nslookup my.patientsknowbest.com sonia.ns.cloudflare.comornslookup my.patientsknowbest.com shane.ns.cloudflare.com
to query one of the authorative nameserver for patientsknowbest.com.
