@stephenw10 thanks for responding -- yup pfSense update solved this particular issue. Now I'm running into TLS/ cert issues on my dockerized graylog setup, which is probably outside the scope of this forum.
Would be nice to have a standard way to securely manage logs in Pfsense -- one that does not encourage people to send logs in the clear.
I know you can just run a local server and have some security with Rules, but would suggest to have a more formal secure integration with Graylog given how popular it seems to be with people here. Also for people that want to monitor more than one network with one Graylog instance
