Strange error in daily logs

Does anyone know what this is.

conntrack: generic helper won't handle protocol 47. Please consider loading the specific helper module.

I assume protocol 47 is Generic Routing Encapulation (whatever that means)

Hello,

You will typically see these types of error messages on VPS systems that are missing specific iptables modules. Your VPS hosting provider is generally the best contact to address the issue or to determine the specific cause.

Thank you.

I have a dedicated server.
Is it just an error or something more sinister.

If it's an error, I can live with it. If it's a security concern, then I'll want to do something about it.

Assuming CSF is installed, at bottom of CSF main page is a "Test IPtables" option. What result does it give you?
