AFW-112 — Collector port already in use ​

Area: Install & collector boot · All support codes · Reference table

Why this happened ​

Another process on the collector host already listens on one of the collector's ports (8080 proxy, 8443 device hop, 9443 PAC-TLS), so that listener was not started. The collector never moves to a different port: devices, PAC files and firewall rules all name these ports.

Fix ​

On the host, find the process (sudo ss -ltnp 'sport = :8443'), stop it or move it to another port, then restart the collector (Collectors page → Restart).


If the fix doesn't resolve it, file a support ticket from the console — your workspace's diagnostics snapshot is attached automatically, so this code reaches support with its context.
