Hello All,

I am trying to execute mt Kibana UI login and it fails.

I checked the logs for the pod and this is what it shows:

[lewellf\_adm@awva-pclif03001 kibana]$ kubectl logs kibana-75f647cf75-5l5lz -n monitoring-tools

and `regenerator-runtime/runtime` separately

Can someone please help me fix this issue?

Hi  
Since your logs show that you're using OpenDistro, I would recommend to raise an issue on their forum.  
Best,  
Matthias
