Problem:

Log Analytics admin console is unreachable.

Possible cause(s):

• Root Cause 1:
  Service is not running
• Root Cause 2:
  Wrong port usage
• Root Cause 3:
  Firewall is blocking the communication

Possible solution(s):

• Solution Root Cause 1:
  To check if the status is running or not:

  sudo systemctl status cerebro

  If the cerebro is not running, you may restart and enable the service:

  sudo systemctl start cerebro
  sudo systemctl enable cerebro

• Solution Root Cause 2:
  
  To access the following services, these ports are used:
  5602 - Admin console, Cerebro.
  
  Check if you have been accessing the correct port; you may interchange ports like 5062 instead of 5602:
  https://<LA_IP>:5602
  
  To confirm if port 5602 is currently being used by a service, run:

  sudo systemctl status cerebro

  If the port is in use, you should see a line indicating it's in the LISTEN state.
   

• Solution Root Cause 3:

  Your local firewall might be blocking the communication,, disabling this should allow things to work properly.
