Also not sure if this makes a difference, but the server used to previously be connected to fleet. It was deleted from the fleet UI, osqueryd uninstalled from the server, and am now trying to re-install/re-enroll it.

Shouldn't matter much that it was previously enrolld.

@zwass Hello, I think I have similar issues. I Have some problems with Windows hosts that hav not been fetched for a long time to Fleet (1 picture). I deleted host from UI, from mysql database and then reinstall osquery. I see in Fleet UI host, but it doesn't fethed. In mysql in table hosts (2 picture) i See it but with diffent node key. Then i saw fleet logs and saw auth error with diffent node key (3 picture). I use hostname like host id, and in mysql I see only one host with this id, no duplicates
