Since we have SSL/TLS enabled in Nginx or Caddy, we need to set <code>tls</code> to <code>true</code>, restart the panel when you are done.</li></ul><p>Agent Configuration</p><ul><li>Log in to the admin panel, copy the one-click install command, and run the one-click install command on the corresponding server to reinstall the agent.</li></ul><p>Enable Cloudflare CDN (optional)</p><p>According to Cloudflare gRPC requirements: gRPC services must listen on port 443 and must support TLS and HTTP/2. So if you need to enable CDN, you must use port 443 when configuring Nginx or Caddy reverse proxy gRPC and configure the certificate (Caddy will automatically apply and configure the certificate).</p><ul><li>Log in to Cloudflare and select the domain you are using. Go to the <code>Network</code> page and turn on the <code>gRPC</code> switch, then go to the <code>DNS</code> page, find the resolution record of the domain with gRPC configuration, and turn on the orange cloud icon to enable CDN.</li></ul></div></div><footer class="page-footer" data-v-7eddb2c4 data-v-07c132fc><div class="edit" data-v-07c132fc><div class="edit-link" data-v-07c132fc data-v-1ed99556><a class="link" href="https://github.com/nezhahq/nezhahq.github.io/edit/main/docs/en_US/guide/q3.md" target="_blank" rel="noopener noreferrer" data-v-1ed99556>Edit this page on GitHub <svg class="icon outbound icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" x="0px" y="0px" viewbox="0 0 100 100" width="15" height="15" data-v-1ed99556><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg></a></div></div><div class="updated" data-v-07c132fc><p class="last-updated" data-v-07c132fc data-v-abce3432><span class="prefix" data-v-abce3432>Last Updated:</span><span class="datetime" data-v-abce3432></span></p></div></footer><div class="next-and-prev-link" data-v-7eddb2c4 data-v-38ede35f><div class="container" data-v-38ede35f><div class="prev" data-v-38ede35f><a class="link" href="/en_US/guide/q2" data-v-38ede35f><svg xmlns="http://www.w3.org/2000/svg" viewbox="0 0 24 24" class="icon icon-prev" data-v-38ede35f><path d="M19,11H7.4l5.3-5.3c0.4-0.4,0.4-1,0-1.4s-1-0.4-1.4,0l-7,7c-0.1,0.1-0.2,0.2-0.2,0.3c-0.1,0.2-0.1,0.5,0,0.8c0.1,0.1,0.1,0.2,0.2,0.3l7,7c0.2,0.2,0.5,0.3,0.7,0.3s0.5-0.1,0.7-0.3c0.4-0.4,0.4-1,0-1.4L7.4,13H19c0.6,0,1-0.4,1-1S19.6,11,19,11z"></path></svg><span class="text" data-v-38ede35f>Let the Agent start/on-line, and the self-test process of the problem</span></a></div><div class="next" data-v-38ede35f><a class="link" href="/en_US/guide/q4" data-v-38ede35f><span class="text" data-v-38ede35f>Real-time channel disconnection/online terminal connection failure</span><svg xmlns="http://www.w3.org/2000/svg" viewbox="0 0 24 24" class="icon icon-next" data-v-38ede35f><path d="M19.9,12.4c0.1-0.2,0.1-0.5,0-0.8c-0.1-0.1-0.1-0.2-0.2-0.3l-7-7c-0.4-0.4-1-0.4-1.4,0s-0.4,1,0,1.4l5.3,5.3H5c-0.6,0-1,0.4-1,1s0.4,1,1,1h11.6l-5.3,5.3c-0.4,0.4-0.4,1,0,1.4c0.2,0.2,0.5,0.3,0.7,0.3s0.5-0.1,0.7-0.3l7-7C19.8,12.6,19.9,12.5,19.9,12.4z"></path></svg></a></div></div></div><!--[--><!--]--></div></main></div><!----><!--]--></div>
