vault dynamic secret failed to renew: lease expired error

TL;DR

A dynamic secret's lease expired because nothing renewed it in time. Renew leases on a schedule inside their TTL, and when the max TTL is reached, fetch a fresh credential instead of renewing.

Error

vault dynamic secret failed to renew: lease expired error

Steps

1. Check the lease's TTL and max TTL. Expected: you see how much life was left.
2. Set up renewal on a timer at a fraction of the TTL (half is typical). Expected: renewals happen well before expiry.
3. Handle the max-TTL case: renewal past it fails, so the code must request a new credential. Expected: no outage at max TTL.
4. Confirm the renewing token itself has permission to renew and is not expired. Expected: the renew call is authorized.
5. Monitor lease lifetimes and alert before expiry. Expected: early warning next time.

When to use

• Database or cloud dynamic credentials expiring unexpectedly.
• Apps that hold long-lived dynamic secrets.

When not to use

• Static kv secrets (no leases).
• Initial issuance failures (different problem).

Tool compatibility

• Vault dynamic secret engines; lease and token TTLs.

Variant phrasings

Same renewal fix.

dynamic credentials stopped working

Check lease state.

Why it happens

Dynamic secrets are rented, not owned. The lease must be actively renewed, and everything has a max TTL after which renewal is impossible.

Edge cases

• The renewing process dying silently is the classic cause; supervise it.
• Clock skew can make a valid lease look expired; check time sync.
• Some engines do not support renewal at all; those always need re-issuance.
