Hi Benoit,

Sorry for your problem. Deleting the node in Rudder to reboostrap it 
should not be done.

There are numerous causes for this very issue, so we created a FAQ entry 
for this:
https://www.rudder-project.org/site/documentation/faq/some-reports-are-in-no-answer-for-a-node/

Usually, it's a DNS issue. Since bootstraping works and then it fails, i 
suppose this is a resolution problem on client side; could you see if 
unticking the "Use reverse DNS lookups on nodes to reinforce 
authentication to policy server"
  on the Adminsitration/Settings page in the Web Interface solves the 
issue ?

Regards,
Nicolas
