Currently, I have GrayLog running as a docker image on an unraid server. Everything is working well. I also have a MS Windows lab environment that I want to forward logs into Graylog with the help of nxlog. I followed the instructions at: https://docs.nxlog.co/userguide/integrate/graylog.html and I don't have any errors, but I also don't have any data. Any ideas on how I can troubleshoot this to determine where my issue is?
