Ansible playbook tasks blocked by Unifi threat detection


I noticed that some Ansible playbook tasks sometimes failed – and it looked completely random. After a lot of digging around firewall rules and vlan isolation which I didn’t change – I noticed that in the Unifi threads flow log there were actually a lot of entries of ‘blocked’ threads coming from my Ansible server (Semaphore UI). After whitelisting the server IP all was good again.
