What happened
A service waited too long for the database to respond.
How to fix it
Check pool size and slow queries. Raising max_conns is occasionally the answer, and occasionally the problem.
Example response
{
"error": "HEN-4101",
"message": "Database timeout",
"status": 504,
"request_id": "req_45dba4"
}Should I retry?
Yes. Retry with exponential backoff and jitter.
