claude-code - 💡(How to fix) Fix [Bug] Model performance regression: Claude Code output quality degraded [1 participants]

[{"error":"AxiosError: timeout of 5000ms exceeded\n at <anonymous> (/$bunfs/root/src/entrypoints/cli.js:120:13282)\n at emit (node:events:92:22)\n at <anonymous> (/$bunfs/root/src/entrypoints/cli.js:119:3321)\n at request (/$bunfs/root/src/entrypoints/cli.js:122:2467)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-28T14:55:23.087Z"}]

TL;DR

The issue with Claude's performance may be related to a timeout error, and adjusting the timeout setting or checking the network connection could be a potential fix.

Guidance

• The error message indicates an AxiosError with a timeout of 5000ms exceeded, suggesting a potential issue with the network connection or the server's response time.
• Verify the network connection and check if other projects are experiencing similar issues to determine if it's a local or server-side problem.
• Consider increasing the timeout value to allow for more time to receive a response from the server.
• Check for any updates to the Claude version, as the issue mentions a specific version (2.1.121) and a comparison to Codex.

Example

No code snippet is provided as the issue does not contain sufficient information to create a relevant example.

Notes

The issue lacks detailed information about the projects and the specific tasks being performed with Claude, which could be helpful in identifying the root cause.

Recommendation

Apply workaround: Increase the timeout value to a higher setting (e.g., 10000ms) to see if it resolves the issue, as the current timeout of 5000ms may be too low for the server's response time.
