Error Signal
401 missing authentication headersWhat's Happening
You're seeing "401 missing authentication headers" and general breakage after a fresh OpenClaw install (specifically reported after upgrading to 2026.3.2). Executable tools are broken or locked, you can't commit to git, read/write files, or interact with the agent effectively. It seems the agent is trying to compress context unprompted and hangs on responses.
The Fix
This is a configuration issue with the tools profile. The default profile in recent versions might be too restrictive.
Hereβs how to fix it:
-
Switch to a more permissive tools profile: Run this command to switch to the
codingprofile, which includes filesystem and execution capabilities:openclaw config set tools.profile coding -
Restart the OpenClaw gateway for the changes to take effect:
openclaw gateway restart
If you still encounter issues, try the coding-extended profile:
openclaw config set tools.profile coding-extended
openclaw gateway restart
As a last resort, downgrading to a previous version also works:
openclaw uninstall
npm install -g [email protected]
Why This Occurs
Recent OpenClaw versions can default to a restrictive tools profile (like messaging) after a fresh install or VM reinstallation. This profile blocks critical agent functions such as executing shell commands (exec) or accessing the filesystem, leading to the "401 missing authentication headers" errors and overall unresponsiveness.
Prevention
Always verify your tools.profile setting after a new installation or significant upgrade. Ensure it includes the necessary capabilities for your workflow (e.g., coding or coding-extended for development tasks). You can check your current setting with openclaw config get tools.profile.
