Known failure modes with their cause and fix: installation, start-up, connections, server access, projects, networks, licences and where to find logs. Each table lists a symptom, its usual cause and what to do. When you contact support, include the product version (Settings → About & support), the licence id and state, the newest start-up log, which installer you used, and whether the port is pinned. Administrators can attach a diagnostics bundle.
