I started to configure graylog, I received logs from my first Linux but when I wanted to configure a GELF with nxlog on a windows this SLF message appeared. and I don’t receive any more log.

I think the SLF4J warning is a red herring and is not related to why you are not getting any logs (there is already an open ticket to clean up that warning).

Please tell us more about how you configuring your nxlog input.

Hello @Vivien

Adding on to @patrickmann
Have you tried a tcpdump on Graylog server?

sudo tcpdump -i eth0 host <remote_ip>
