If your logs are not appearing in Graylog, here are a few things to check:

1. Make sure Graylog has a GELF TCP input listening on port 12201, and that TLS is not enabled on this input.
2. In the Stackhero dashboard, under "Configure", confirm that port 12201 is set up with TCP and TLS enabled under "Input ports".
3. Check that the firewall rules in Stackhero show port "12201/tcp" as "ACCEPT", ideally at position #1 with the source set to 0.0.0.0/0 for testing.
4. In the Graylog admin panel under "Search", ensure you are viewing logs from the last hour and set the view to update every second to see new messages as they arrive.
