 * Hello
 * I’m experiencing persistent issues connecting Jetpack to WordPress.com from my
   site [https://zulucow.co.uk](https://zulucow.co.uk).
 * Despite extensive debugging and confirmation from my hosting provider (IONOS),
   Jetpack fails to complete the connection, returning:
 * SSL Failed: WordPress reports no SSL support
 * and
 * Your server did not successfully connect to the Jetpack server using HTTP
 * **Troubleshooting Already Completed**
 * **Server & Configuration**
    - Site served over HTTPS with a valid SSL certificate (Let’s Encrypt)
    - is_ssl() now correctly returns true (verified via WP-CLI and Jetpack status)
    - wp-config.php includes:define(‘FORCE_SSL_ADMIN’, true);$_SERVER[‘HTTPS’] =‘
      on’;$_SERVER[‘SERVER_PORT’] = 443;$_SERVER[‘REQUEST_SCHEME’] = ‘https’;
 * **Outbound HTTPS Works**
    - I can successfully connect to [https://jetpack.com](https://jetpack.com) using
      both:
       * WP-CLI (curl -I)
       * PHP test script from browser (curltest.php)
 * **Outbound to jetpack.wordpress.com Fails**
    - Direct curl to [https://jetpack.wordpress.com/jetpack.test](https://jetpack.wordpress.com/jetpack.test)
      hangs indefinitely when run from a browser-accessed PHP script
    - This mirrors Jetpack’s own test, which returns:cURL error 28: Connection timed
      out after 5001 milliseconds
 * **Hosting Provider (IONOS) Confirms No Restrictions**
    - They have confirmed there are no firewall or outbound port restrictions from
      my VPS to the internet
    - No ModSecurity, WAF, or rate limits are interfering
 * **Troubleshooting Mode**
    - I have enabled Jetpack Troubleshooting Mode and confirmed the issue persists
      with all other plugins disabled and the default theme active
    - This rules out any plugin or theme conflicts
 * **Key Symptoms**
    - Jetpack Debugger at /wp-admin/admin.php?page=jetpack-debugger fails HTTP and
      HTTPS connectivity tests
    - WP-CLI shows:
       * is-https: https
       * ssl: (blank)
       * blog_id: 0
    - All jetpack status tests pass except the outbound connection and sync ones
 * **Request for Help**
 * Can someone from the Jetpack team confirm whether:
    - There are any known restrictions or blocks on traffic from my server IP?
    - The endpoint [https://jetpack.wordpress.com/jetpack.test](https://jetpack.wordpress.com/jetpack.test)
      is available and accepting connections?
    - There’s anything further I can do to manually pair the site via tokens if 
      the automatic process fails?
 * Happy to provide full terminal output, curl logs, or a full diagnostic summary.
   Many thanks in advance for your help.

 * Hi [@eddyallen91](https://wordpress.org/support/users/eddyallen91/) –
 * This all sounds pretty frustrating. I appreciate your troubleshooting so far.
   We don’t have any blocking on your IP, so you wouldn’t be encountering issues
   there. Additionally, we can’t manually pair the tokens, so we’ll need to get 
   this working.
 * I made an adjustment on our end to how Jetpack attempts to communicate with your
   site. As a next step, please uninstall and reconnect Jetpack. That will cycle
   the connection and _might_ fix the issue.
 * Let us know if you can connect after that.

 * Hi there, [@eddyallen91](https://wordpress.org/support/users/eddyallen91/),
 * Do you have updates about that, do you still need help? We usually close inactive
   threads after one week of no movement, but we want to make sure we’re all set
   before marking it as solved. Thanks!
