WebFinger endpoint is not accessible & PHP warning

    Hi!

    The site health check shows a critial issue “WebFinger endpoint is not accessible” but there are no details when opening the accordion item.

    Beside that, the Query Monitor Plugin shows two PHP warnings “Array to string conversion” at these locations:

        wp-content/plugins/activitypub/includes/wp-admin/class-health-check.php:245
        sprintf()
        wp-content/plugins/activitypub/includes/wp-admin/class-health-check.php:245
        Activitypub\WP_Admin\Health_Check::is_webfinger_endpoint_accessible()
        wp-content/plugins/activitypub/includes/wp-admin/class-health-check.php:169
        Activitypub\WP_Admin\Health_Check::test_webfinger()
        wp-admin/includes/class-wp-site-health.php:194
        WP_Site_Health->perform_test()
        wp-admin/includes/class-wp-site-health.php:145
        WP_Site_Health->enqueue_scripts()
        wp-includes/class-wp-hook.php:324
        do_action('admin_enqueue_scripts')
        wp-admin/admin-header.php:123

    How can I debug this? Webhoster Netcup can’t help.

    Best regards
    Matthias

    Interesting, thanks for reaching out!

    You could check the response for https://your.domain/.well-known/webfinger?resource=acct%3Aapplication%40your.domain where “your.domain” is your domain.

    Could you let us know what you come up with, I’d like to fix that for everyone if possible.

    Hi @obenland ! Thanks for your quick reply.

    I tested:

    https://pabst-photo.com/.well-known/webfinger?resource=acct:[email protected]

    The result is this:

    {
      "subject": "acct:[email protected]",
      "aliases": [
        "https://pabst-photo.com/?author=0",
        "https://pabst-photo.com/@click",
        "https://pabst-photo.com/"
      ],
      "links": [
        {
          "rel": "self",
          "type": "application/activity+json",
          "href": "https://pabst-photo.com/?author=0"
        },
        {
          "rel": "http://webfinger.net/rel/profile-page",
          "type": "text/html",
          "href": "https://pabst-photo.com/?author=0"
        },
        {
          "rel": "http://ostatus.org/schema/1.0/subscribe",
          "template": "https://pabst-photo.com/wp-json/activitypub/1.0/interactions?uri={uri}"
        }
      ]
    }

    Looks like everything works as expected! It’s still showing the error in Site Health? 🤔

    I wonder if there was an unexpected/faulty reply that was cached, and keeps failing this check.

    This is a guess as to what the transient key would be to purge the cache: webfinger_559ceaca286ae15ba8cd5a99741116e0. If you have access to WP CLI, you could try removing it with wp transient delete webfinger_559ceaca286ae15ba8cd5a99741116e0. Or in PHP delete_transient( 'webfinger_559ceaca286ae15ba8cd5a99741116e0' );.

    Regardless, this should self-heal within a week and doesn’t affect the functionality of your site or the ActivityPub plugin.

    I purged the transient cache and now the site health check is good. 🎉

    Thank you, Konstantin!

    The check is the one issue, but it should never have a PHP warning 😳

    I will check why this happend!

    Thanks for reporting @matthiaspabst
