Ohne mir erkenntlichen Grund bekommen die Besucher oder ich als Admin immer öfter  eine Fehlermeldung

 

/concrete/vendor/zendframework/zend-http/src/Client/Adapter/Curl.php:453 Read timed out (1000)

 

und die Seite lädt nicht.

Kann ich in der curl.php etwas ändern,

Ohne den Zugriff komplett zu verlieren.
