IPs not being banned after decision

crowdsec
1

We had CS working at one point… at some point (we believe after the version upgrade to 1.1) it stopped blocking IPs.

When we do a decisions list, it shows the IPs as blocked…
When we look at: /crowdsec-firewall-bouncer.log, it shows that it is adding/deleteing decisions

I suspect that nftables is not working properly…

I’ve looked at the other threads, but I don’t see guidance for how/what to troubleshoot when the blocks don’t work.

Thanks.

Hello @haldrich !

Can you provide a bit more information, like what your nftables content looks like ? nft list table crowdsec or equivalent ?

Thanks,

We got it to work, somewhat mysteriously, by uninstalling and reinstalling the firewall…
Thanks.
