The last system check point fails for three reasons:

1) No microphone connection;
2) No connection to camera;
3) Low speed or unstable internet connection.

Try to go to the History page: chrome://settings/clearBrowserData open «Advanced»
In «Time range» choose «All time», next select all checkboxes, except "Passwords and other sign-in data" and press "Clear data".


Then restart the system on the computer according to the instructions below. If you don’t know your account password, then skip this step. To restart the system, follow these steps: 

1. Press Win + R
2. Enter cmd and press "Run"
3. In window enter command: shutdown /f

After this open only one browser and try to pass check again.

If system check also fails at the point -please, check your microphone. If the microphone doesn’t work or incorrectly set by default, the last point of system check also won’t work. 

To change the connected microphone, follow these steps:

1. Press Win+R

2. Enter mmsys.cpl

3. Then open "Recording" and choose the microphone which have a green volume indicator when you speak. Click on it and choose "Default", then click "Apply":


If there are no microphones in menu, click right mouse button on empty area and choose "Show Disabled Devices". Right-click on the needed microphone and choose «Enable»:


Then right-click on microphone and choose "Properties", open «Listen» and check the following points and click "Apply": 



Open «Levels» and check microphone volume level. If an indicator of volume level has crossed the speaker – click on it to enable it. Confirm changes by clicking OK:


Go to the page: chrome://settings/content/microphone and make sure that there is the same microphone, which shows a green indicator and set to "Default":


Similarly, check that the correct camera is selected in chrome://settings/content/camera

Then open  choose camera in the upper right corner and check that the correct camera is displayed. If the wrong camera is displayed – click on "Settings" and choose right camera in "Camera" field.


If you haven’t working microphone or camera, then you need to connect any active one, since the system check will not work without any working microphone connected. If you have a built-in camera and microphone, then try to connect a headset and separate webcam. 

After completing following recommendations, try to pass the system check again.

If the system check also fails at the last point, please make sure that your Internet connection speed is enough.

Press "Test" button, wait until the end of the check, after receiving the result, scroll to the bottom of the page, click "copy to clipboard", paste it into the letter (Ctrl + V) and send us the result.
