# Current evidence does not cover this case

_Claude Code "Stream idle timeout - partial response received"_

**Already tried:** Values under 5 minutes are ignored; The stream is probably really stalled

You have tried the fixes the evidence supports and the error remains, so this guide will not guess further.

**What would help:** The Claude Code version and surface, the value of CLAUDE_STREAM_IDLE_TIMEOUT_MS, what Claude was doing when the stream went silent, and how often it happens.

- `activity` (What Claude was doing when it went silent): writing-large-file | long-tool-run | thinking | idle | unknown
- `frequency` (How often it happens): once | several-per-day | most-long-tasks | unknown
- `network` (Network path): direct | corporate-proxy | vpn | unknown
- `surface` (Where Claude Code runs): cli | desktop | ide-extension | web-or-cloud | sdk | unknown
- `timeout_env` (CLAUDE_STREAM_IDLE_TIMEOUT_MS): unset | set | unknown

Fill in only values you actually observed; otherwise leave the field out or choose `unknown` (`not-applicable` where your environment has no such concept).

Send at least one field. Resubmit with `report=ygEllaJuRrBPvAPD` to change this report.

**Evidence:** The branches above are all the evidence we have; Anthropic has not explained the stalls in the source thread.
