Amazon Q chat stuck starting? Use logs to locate the failing stage.

A startup screen and a request that receives an error are different failures. Preserve the current project state, then use Amazon Q logs to identify whether the problem is local, authentication, network, or chat processing.

Do this first: Open Amazon Qs Show Logs view in the IDE, or collect the local Q CLI logs if using the command line. Review only the relevant error lines and redact code, file paths, account identifiers, and other sensitive data before sharing.

What the failure looks like.

The IDE chat panel remains on a startup/loading state, or an active request returns a repeated generic error. Record which interface is affected and whether the issue begins before or after a request is sent.

Why it happens.

AWS documents separate IDE and CLI log paths, including qchat.log and chat.log for the CLI, and lists authentication, network, and feature-specific errors as useful signals. Those instructions help collect evidence; they do not confirm one root cause for this symptom.

Fix it without losing the task.

Record whether the issue is in VS Code, JetBrains, or Amazon Q CLI, and whether the failure happens before a chat request.

For IDE extensions, open Show Logs. For Q CLI, use the official qlog locations and compare qchat.log with chat.log around the failure timestamp.

Look for a concrete authentication, network, initialization, or chat-processing error. Redact sensitive content before sharing logs.

After one evidence-based change, reopen the affected surface and send a small test request. Verify the project diff separately from chat availability.

What the next AI should receive.

Amazon Q surface (IDE or CLI), client and extension versions, exact startup/request status, timestamp, redacted relevant log lines, task goal, and current project diff.

First safe action

Capture the log error and timestamp before signing out, reinstalling, or resetting local state. For an IDE extension, use its Show Logs control; for Q CLI, check the documented qlog files.

Evidence boundary

The AWS logging guide explains how to gather diagnostics and warns that logs may contain conversation content, file paths, code, and account details. It does not document a universal repair for a stuck startup screen.

Diagnostic checkpoint

Do not treat a loading panel as proof of an AWS backend overload. First determine whether a request was sent and inspect the corresponding local log entry.

How ShardStitch helps.

ShardStitch can preserve the local project diff and the task summary while you troubleshoot the Amazon Q client. It does not access Q logs automatically or repair AWS authentication, network, or service state.

Official diagnostic source.

AWS: Accessing and using Amazon Q Developer logs documents the IDE Show Logs flow, Q CLI log locations and files, and sensitive-data cautions. It is a diagnostic reference, not a confirmed fix for this specific loading symptom.

FAQ.

Does Amazon Q showing Chat is starting up prove a backend outage?

No. It may be a local extension, authentication, network, or service problem. Use the corresponding Q logs to identify the failing stage before assigning a cause.

Can I share the full Amazon Q log file publicly?

Review it first. AWS warns that logs can contain conversation content, code, file paths, command output, account IDs, and resource names. Share only the minimum redacted lines needed.

Scope note: This is a log-led diagnostic for an Amazon Q startup or response problem. It does not claim a confirmed widespread defect or attribute the behavior to ModelOverloadedError without matching logs.
