Need help understanding Timeout with bw: SpinningDown

This is the redacted Timeout Error:

“Timeout performing HGETALL (5000ms), next: HGETALL {REDACTED_KEY}, inst: 155, qu: 0, qs: 0, aw: False, bw: SpinningDown, rs: ReadAsync, ws: Idle, in: 0, last-in: 0, cur-in: 0, sync-ops: 139378, async-ops: 683, serverEndpoint: {REDACTED_SERVER}, conn-sec: 25024.5, aoc: 1, mc: 1/1/0, mgr: 10 of 10 available, clientName: {REDACTED_MACHINE_NAME}(SE.Redis-v2.6.122.38350), PerfCounterHelperkeyHashSlot: 12479, IOCP: (Busy=0,Free=1000,Min=8,Max=1000), WORKER: (Busy=30,Free=32737,Min=8,Max=32767), v: 2.6.122.38350 (Please take a look at this article for some common client-side issues that can cause timeouts: https://stackexchange.github.io/StackExchange.Redis/Timeouts)”

I've looked at the timeout documentation here: https://stackexchange.github.io/StackExchange.Redis/Timeouts
I couldn't find the reason there. (I have IOCP BUSY=0, in=0, mgr=10/10)

Any help is welcome.

Start with the linked Timeouts documentation and the redacted timeout diagnostic, especially bw: SpinningDown during HGETALL. Done would require an evidence-based explanation of the reported state or a clearly documented client issue and next steps; no source file or test is named in the issue.
