Resolution when custom variable go missing while trying to add custom variables.

After reviewing portal logs, it is observed that queries to port 2999 fail.

  • Validate on OS that port 29999 is open by viewing netstat or iptables -L
  • If port 29999 is open, validate if IPv6 is disabled. If it is disabled, do the following,
  1. Login to the looker machine
  2. Run: sudo docker exec -it looker-container bash (this allows us to execute bash commands in the looker-container)
  3. Run: vi nginx.conf (vi editor so we can edit nginx.conf)
  4. Type the following: :36 Hit enter. (This will take you to line 36.)
  5. Type: i # - this comments out the ipv6 line in the nginx config
  6. Hit the escape key and then type: :wq! - this writes and quits the vi editor
  7. Type: exit
  8. Run: sudo docker restart looker-container (this restarts the looker container)
  9. Run: sudo docker exec -it looker-container curl -vk https://127.0.0.1:2999 (this is to validate that communications over port 29999 are working).
