Resolución de problemas con el entorno de juego de su campo

Por favor, intente lo siguiente:

1. Intente ver la lección en un ventana de incógnito. 
   1. Si la lección se reproduce sin problemas, prueba a comprobar la extensión, el plugin o el programa cortafuegos de tu dispositivo para ver si es necesario reconfigurarlo o desactivarlo.  
2. If you’re encountering the issue while watching the lesson on your college or academies network, try watching the lesson on a non-company / non-academy network instead. If you’re able to watch the lesson without any issue, please report the issue to their IT team.
3. Try a different browser. If you’re not already using Google Chrome, we recommend using it, as we’ve found it works best to watch NailKnowledge courses. 
4. Despeja tu browser’s cookies and cache y reinícielo antes de volver a intentarlo. 
   1. If you have a lot of browser tabs open, close most of them except the one you’re using to watch the course.
   1. Check your versión del navegador y actualícelo si es necesario. 
5. A minimum internet speed of 5Mbit or 800kbps is required to watch a NailKnowledge course on your device. Test your internet connection speed to make sure your environment meets this and that your system meets our requirements.  If your internet speed is low, try watching the course during non-peak hours when your internet connection is stronger.
6. If you can’t hear any audio, double-check to see that the lesson player volume is turned up and that the lesson is not muted. Check the sound settings on your device.
7. Reinicie el ordenador y los dispositivos de red (módems/conmutadores/routers).
