502 Server error

[Doctorrr]

After several hours of a normal work and some rest,
i came back to 502 Server error + errors in Chrome console::

blob:https%3A//mydomain.com/29d5804c-f27f-45aa-8e77-53a90a9096a4 Failed to load resource: the server responded with a status of 404 (Not Found)

My configuration:

require_once( $_SERVER['DOCUMENT_ROOT'].'/php-console/src/PhpConsole/__autoload.php' );
$connector = PhpConsole\Helper::register();

if($connector->isActiveClient()) {
    $handler = PC::getHandler();
    $handler->start();

    $connector->setSourcesBasePath($_SERVER['DOCUMENT_ROOT']);
    $connector->setPassword( '12345' );
    $connector->enableSslOnlyMode();

    $evalProvider = $connector->getEvalDispatcher()->getEvalProvider();
    $evalProvider->addSharedVar('uri', $_SERVER['REQUEST_URI']);
    $evalProvider->addSharedVarReference('post', $_POST);
    $connector->startEvalRequestsListener();

}

Updated Chrome on Win 10.

Can't reproduce it. Try to clear cookies and reinstall extension.

maybe the header too big ,you can see the nginx error log (upstream sent too big header while reading response header from upstream)
