1. Describe your incident:
When I started using HTTPS, the inputs show NOT RUNNING, and cannot get any information under System >> nodes.

2. Describe your environment:

  • OS Information:

I have Graylog & mongo DB installed in one machine and OpenSearch installed in another Machine.

GrayLog Version 5.2
