Atera troubleshooting: missing agents, alert timing, scripts, patches and Splashtop
Working the problems Atera's knowledge base documents most: agents that never appear in the console or show offline, MSI errors 2203, 2502 and 2503, golden images that create duplicates, agents that must be reinstalled rather than upgraded; how quickly Atera raises and resolves alerts and refreshes device data, and how the agent health score is calculated; scripts that fail (file type, silent switches, run context, exit codes); failed OS patches and patch lists that don't match Windows; and Splashtop sessions that won't connect.
