Security. Statistics. Performance features. Connections to WordPress.com.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But when that connection gets sick, Jetpack has a habit of presenting symptoms without making the underlying diagnosis immediately obvious.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before you start deactivating plugins, changing firewall settings, reinstalling WordPress, or blaming your hosting company, there\u2019s a much easier place to start: <strong><a href=\"https:\/\/jptools.wordpress.com\/debug\/\" target=\"_blank\" rel=\"noreferrer noopener\">Jetpack Debug<\/a>.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Diagnosis: Jetpack Isn\u2019t Talking to Your Website<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A surprising number of Jetpack problems aren\u2019t really problems with the feature you\u2019re trying to use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They\u2019re communication problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack needs to be able to communicate between your WordPress website and WordPress.com. When something interrupts that conversation, seemingly unrelated Jetpack features can begin behaving strangely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Jetpack Debug tool is essentially a quick medical exam for that connection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Enter your website address and let it run its tests.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack\u2019s own support documentation recommends the tool for identifying connection problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms That May Send You to the Debugger<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You might want to give your website a Jetpack checkup if you\u2019re seeing things such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Jetpack refusing to connect<\/li>\n\n\n\n<li>Features suddenly stopping<\/li>\n\n\n\n<li>Backup or Scan connection problems<\/li>\n\n\n\n<li>XML-RPC errors<\/li>\n\n\n\n<li>Connection timeouts<\/li>\n\n\n\n<li>HTTP errors<\/li>\n\n\n\n<li>WordPress.com saying it cannot communicate with your site<\/li>\n\n\n\n<li>Jetpack behaving normally one day and irrationally the next<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Think of these as symptoms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Debug tool helps you get closer to the actual disease.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Use Jetpack Debug<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fortunately, this examination doesn\u2019t require a white coat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Go to <a href=\"https:\/\/jptools.wordpress.com\/debug\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/jptools.wordpress.com\/debug\/<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Enter the full address of your WordPress website and run the test.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your site is associated with your WordPress.com account, the tool may also allow you to select it directly. If it isn\u2019t listed, you can simply enter the URL manually.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the connection passes its tests, Jetpack says you should receive an indication that everything looks good.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If it doesn\u2019t?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now you have something useful to work with.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Diagnosis: XML-RPC Trouble<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the important pieces of the Jetpack connection is WordPress\u2019s <code>xmlrpc.php<\/code> file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack uses it to communicate with your website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your hosting company, security plugin, firewall, CDN, or another system blocks that communication, Jetpack may develop a serious case of <strong>Communication Anxiety Disorder<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack recommends checking your XML-RPC endpoint when troubleshooting connection problems. A normal WordPress installation should respond to a browser request for <code>xmlrpc.php<\/code> with a message indicating that the XML-RPC server accepts POST requests only.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 404, 403, or other unexpected response can point you toward the real problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Another Common Diagnosis: An Overprotective Firewall<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Security is good.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A firewall that protects your website is good.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A firewall that protects your website so enthusiastically that legitimate services can no longer reach it is less good.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack specifically notes that a firewall, web application firewall, hosting rule, or security plugin can block WordPress.com requests to <code>xmlrpc.php<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In other words, your website may be suffering from <strong>Security Trust Issues<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The site has become suspicious of everyone \u2014 including Jetpack.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The prescription may involve adjusting the security rule rather than changing Jetpack itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">HTTP Errors Are Clues, Not Just Bad News<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The debugger may also return familiar HTTP status codes such as:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>400, 401, 403, 404, 408, 429, 500, 502, 503, or 504.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Don\u2019t treat the number as meaningless technical gibberish.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s a clue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack maintains guidance explaining what these HTTP responses can mean when its service is attempting to communicate with WordPress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a 500 error points you in a very different direction from a 403 error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One suggests the server itself is having trouble completing the request.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The other may suggest that the request is being forbidden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Same patient. Different diagnosis. Different treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cloudflare Can Occasionally Complicate the Conversation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cloudflare and other content delivery or security services can add another layer between Jetpack and your WordPress installation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That layer is usually helpful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes it gets a little too involved in the relationship.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack documents cases where sites using Cloudflare or other proxy services can encounter connection problems, including XML-RPC-related errors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If Jetpack Debug points toward that part of your configuration, investigate the proxy or firewall rules before performing major surgery on WordPress.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Prescription: Diagnose Before You Start Changing Things<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the part we really like about Jetpack Debug.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It encourages the correct troubleshooting order.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Test first. Change things second.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Far too many WordPress troubleshooting sessions begin like this:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Deactivate something.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Refresh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Change something else.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Refresh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clear every cache known to mankind.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Refresh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reinstall something.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Refresh.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Forget what you changed three steps ago.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now the website has three new problems and nobody remembers what the original problem was.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s not debugging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s exploratory surgery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A diagnostic tool gives you evidence before you begin treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If Jetpack Debug Finds a Problem<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once the debugger gives you an error, use that error to narrow the investigation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the diagnosis, the treatment might involve checking:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your Jetpack connection<\/li>\n\n\n\n<li><code>xmlrpc.php<\/code><\/li>\n\n\n\n<li>Your hosting firewall<\/li>\n\n\n\n<li>A WordPress security plugin<\/li>\n\n\n\n<li>Cloudflare or another CDN<\/li>\n\n\n\n<li>SSL\/HTTPS configuration<\/li>\n\n\n\n<li>Plugin conflicts<\/li>\n\n\n\n<li>Theme conflicts<\/li>\n\n\n\n<li>Server configuration<\/li>\n\n\n\n<li>PHP errors<\/li>\n\n\n\n<li>WordPress Site Health<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Jetpack\u2019s current troubleshooting documentation covers these areas in considerably more detail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important point is that you now have a direction.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don\u2019t Immediately Reconnect Jetpack for Every Problem<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is worth mentioning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Disconnecting and reconnecting Jetpack can help with some connection problems, and Jetpack provides a procedure for doing so. But reconnecting isn\u2019t a universal cure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, if a firewall is actively blocking WordPress.com from reaching your site, reconnecting Jetpack doesn\u2019t remove the firewall rule. Jetpack specifically recommends investigating the block instead.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treat the disease, not merely the symptom.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your website will appreciate it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our Prescription<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If Jetpack starts acting strangely, resist the urge to start randomly changing settings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Visit <a href=\"https:\/\/jptools.wordpress.com\/debug\/\" target=\"_blank\" rel=\"noopener\">https:\/\/<\/a><a href=\"https:\/\/jptools.wordpress.com\/debug\/\" target=\"_blank\" rel=\"noreferrer noopener\">jptools<\/a><a href=\"https:\/\/jptools.wordpress.com\/debug\/\" target=\"_blank\" rel=\"noopener\">.wordpress.com\/debug\/<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Run the test.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Read the diagnosis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then start troubleshooting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It takes only a moment, costs nothing, and may save you from an afternoon of unnecessarily performing open-heart surgery on a perfectly innocent WordPress installation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes your website doesn\u2019t need rebuilding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It just needs a proper diagnosis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jetpack can do a lot for a WordPress website.
