If a federation request fails, +Synapse will mark the destination homeserver as offline, preventing any future requests +to that server for a "cooldown" period. This period grows over time if the server +continues to fail its responses +(<a href="https://en.wikipedia.org/wiki/Exponential_backoff">exponential backoff</a>).</p> +<p>Admins can cancel the cooldown period with this API.</p> +<p>This API resets the retry timing for a specific remote server and tries to connect to +the remote server again. It does not wait for the next <code>retry_interval</code>. +The connection must have previously run into an error and <code>retry_last_ts</code> +(<a href="#destination-details-api">Destination Details API</a>) must not be equal to <code>0</code>.</p> +<p>The connection attempt is carried out in the background and can take a while +even if the API already returns the http status 200.</p> +<p>The API is:</p> +<pre><code>POST /_synapse/admin/v1/federation/destinations/<destination>/reset_connection + +{} +</code></pre> +<p><strong>Parameters</strong></p> +<p>The following parameters should be set in the URL:</p> +<ul> +<li><code>destination</code> - Name of the remote server.</li> +</ul> + + </main> + + <nav class="nav-wrapper" aria-label="Page navigation"> + <!-- Mobile navigation buttons --> + <a rel="prev" href="../../../admin_api/version_api.html" class="mobile-nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + <a rel="next" href="../../../manhole.html" class="mobile-nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + <div style="clear: both"></div> + </nav> + </div> + </div> + + <nav class="nav-wide-wrapper" aria-label="Page navigation"> + <a rel="prev" href="../../../admin_api/version_api.html" class="nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + <a rel="next" href="../../../manhole.html" class="nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + </nav> + + </div> + + <script type="text/javascript"> + window.playground_copyable = true; + </script> + <script src="../../../elasticlunr.min.js" type="text/javascript" charset="utf-8"></script> + <script src="../../../mark.min.js" type="text/javascript" charset="utf-8"></script> + <script src="../../../searcher.js" type="text/javascript" charset="utf-8"></script> + <script src="../../../clipboard.min.js" type="text/javascript" charset="utf-8"></script> + <script src="../../../highlight.js" type="text/javascript" charset="utf-8"></script> + <script src="../../../book.js" type="text/javascript" charset="utf-8"></script> + + <!-- Custom JS scripts --> + <script type="text/javascript" src="../../../docs/website_files/table-of-contents.js"></script> + </body> +</html> \ No newline at end of file |
