Troubleshooting information (The chime connectivity checker):

Troubleshooting Testing (to see if all tests are passed)

The first thing to check if you are not able to connect to meeting rooms is to follow this link:

https://app.chime.aws/check# and check if there are no block IP addresses/domains.

If your device passes all the tests – You are ready to use Amazon Chime!

 In case of the IP addresses are blocked:

    It will generate a time out error

There are three ways you can get rid of these errors:

  1. Turn off – if you are using any private VPN/proxy

  2. Get these IP addresses unblocked from your Internet Service Provider

  3. Try using some proxy/VPN – if that works for you

 

Troubleshooting Guide (If all the tests are passed)


The user should allow the browser when it asks to access the microphone and camera. (Camera, Mic should be set to allow)

 

Before clicking on the join button –  Sound & Video can be tested by clicking on the respective “Test Video” and ‘Test Sound Button”

 After joining the meeting:   mic, sound and video should be "ON" (Blue), Grey means it is "OFF"
