Symptoms&lt;/h2>
&lt;p>The &lt;code>clw-auth-invalid&lt;/code> error in OpenClaw manifests during API initialization or authentication handshakes, typically when calling &lt;code>clw_init()&lt;/code> or &lt;code>clw_authenticate()&lt;/code>. This error indicates that the provided credentials or token are rejected by the OpenClaw authentication server.&lt;/p>
&lt;p>Common symptoms include:&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#f8f8f2;background-color:#282a36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-fallback" data-lang="fallback">&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>clw_auth_invalid: Authentication failed. Invalid or malformed token provided.
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>Or in verbose logging:&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#f8f8f2;background-color:#282a36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-fallback" data-lang="fallback">&lt;span style="display:flex;">&lt;span>[ERROR] clw_client.c:147: clw_http_request() failed with HTTP 401 Unauthorized
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>[ERROR] Response body: {&amp;#34;error&amp;#34;: &amp;#34;clw-auth-invalid&amp;#34;, &amp;#34;message&amp;#34;: &amp;#34;Token signature invalid or expired&amp;#34;}
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>Applications may crash, hang, or fallback to offline mode. On Linux/macOS, you might see this in &lt;code>dmesg&lt;/code> or &lt;code>journalctl&lt;/code> if OpenClaw is linked to system services:&lt;/p></description></item></channel></rss>
