QOS Downlink, only filters to Default

Hi all. Please help. QOS has been working great but recently the 2xx Downlink only filters to Default. I reset everything but still, only Default gets filtered.

Please suggest where I can start to troubleshoot

Ok I traced it down to iptables not loading module tx_mark.
Any suggestions apart from reinstalling?

Edit: On my machine the module is called xt_mark?

I’m having a similar issue, I have downlink port 443 set to go to webtraffic class, and almost everything goes to default, even though 99% of the connections are on tcp port 443.

Is there a way to see which connections are being filtered to which class so I can verify if they are working?

What are your rules?
