Error
SMTP timeout after 3 retries
AI diagnosis
The SMTP relay rejected the connection after 3 retries — not a workflow logic error.
Reasoning (always shown — never a black box)
The failing node ("Send Email", Node 4) times out at exactly 4200ms, three times in a row, with an identical error each time ("SMTP timeout after 3 retries"). That pattern — same node, same duration, same message, no variation in payload across attempts — rules out bad input data or a workflow logic bug; a genuine data issue would fail differently between attempts. Cross-referencing the connected n8n instance's other workflows in the same window shows two more SMTP-bound nodes failing in the same 15-minute span, which points to the mail relay itself being unreachable or rate-limiting, not this workflow.
Suggested fix
Retry the execution — this class of failure (transient relay unavailability) typically clears within minutes, and the workflow has no side effects before the failing node that would make a retry unsafe.
