Wireguard TLS client not connecting
Hey, I'm trying to get my hetzner wireguard vps working with crowdsec.
I followed the TLS guide with cfssl from your website and that's working great in my local network so far. I made an unbound DNS overwrite to "security.localdomain" which includes my local crowdsec ip (192.168...) and the wireguard ip (10.0.0.3) in opnsense, installed all ecdsa521-certificates for the bouncer and agent. Worked more or less flawlessly except with my wireguard connected server.
I added the security.localdomain in the /etc/hosts file of the VPS and installed the ca-intermediate cert in /etc/ssl/certs IIRC and I'm able to ping the domain with correct WG IP address, but the lapi still refuses any connection. It worked without any TLS certficiates.
ping security.localdomain or ping 10.0.0.3 are all connecting and wg is up and running....
Get no Heartbeat from Home Assistant Crowdsec AddOn
Hey there, I installed the Crowdsec AddOn on my Home Assistant Server. The server is a Raspberry Pi with the Home Assistant OS.
I disabled the LAPI via the GUI and registered the Home Assistant instance by the following commands. The commands were executed via the Crowdsec Terminal on the GUI.
```
sudo cscli lapi register -u http://192.168.1.1:8080...
How do you write a custom bouncer script fed from stdin ?

ENROLL_KEY and Auto-Accept in Crowdsec Console ?
Hey,
Is there a way to have an auto-accept of security engines in CrowdSec Console ? I thought using the ENROLL_KEY would help with that but it looks like I still have to always accept the enrolment online.
Did I miss something ?...
New how-to for crowdsec for haproxy on opnsense
Hello. I am almost certain that this is the wrong place for this, but I wanted to mention that I have created a how-to on the OPNSense forum, it is here https://forum.opnsense.org/index.php?topic=44839.0 . I hope I haven't broken any rules.

CrowdSec for CloudPanel/WordPress websites
Hi All - I am new to CrowdSec. I am running WordPress sites on the CloudPanel (Ubuntu 24.04 LTS server). I have installed CrowdSec on it by following the installation guide https://docs.crowdsec.net/u/getting_started/installation/linux. I have also enrolled the engine to the CrowdSec console. Is this enough for the setup or I am missing something else? Please guide.
Further, In the community edition of CrowdSec, I can subscribe to 3 blocklists. Can you please suggest the relevant blocklists to subscribe to?
Thank you for the support!...
NPMplus won’t connect to api
I have an unraid server with a reverse proxy setup with NPMplus, a fork of NPM with a built in bouncer. I have a custom docker network setup and I’ve generated an api key and put it in the crowdsec.conf file within the app data of npmplus. It’s also worth noting I’m using cloudflare proxy with real ip passthrough setup in nginx. The ports are all right from what I can see and so is the api key. Blocked IPs still connect and the bouncer metrics list never updates. Trying to curl from the npmplus container to the crowdsec container gives me an error 401… I see a similar 401 error in the crowdsec container log coming from the correct ip.
I’m a bit stumped on what to try next...
how to get notification variables
I'm trying to wrap my head around the syntax of notification variables, please be patient
"title": "{{.Type }} {{ .Value }} for {{.Duration}}",
I was reading this documentation but I do not understand how to map the parsed values to the notification variables, in order to create custom messages, can someone please show me some example?...Ban all IPs parsed from a specific acquisition
I'm trying to find the best way to create a trigger scenario where all detected IPs from aquis.d/myacquis.yaml, that collects nginx logs, are banned.
What's the cleanest way to achieve that? Should I add a label in the aquisition file and create a scenario where I filter by that?
I'm reading the documentation and watching academy videos, but I would appreciate a syntax kickstart, thank you...
Inactive bouncers
Hi, I opened my console yesterday and saw this. I didnt do anything to my setup.
Somehow my CF and Traefik bouncers went inactive and active again. I also see the IP addresses now at the end of the bouncer names.
What could be the cause and how to remove the inactive bouncers?...
Instant attack notification stays disabled

On the Alerts page it's not possible to activate the Instant attack notification. It first says Enabled 'v', but when returning to the Alerts page it's off.
Under Activity it says "Am I Under Attack? feature has been disabled.". ...
Max number of machines a LAPI can handle
Hi.
Just wondering if there is an upper limit on the number of machines a single LAPI can handle? For example, if I'm reselling VPS WordPress hosting to clients I could eventually end up with hundreds of machines. Ideally they'd all connect to a single LAPI so they can use a single shared db. Could it handle that kind of load?
Cheers...
Query local api for scenario containing http
Hi,
I have read the documentation here : https://docs.crowdsec.net/docs/next/local_api/bouncers/
I see that we can query the LAPI for a specific IP, but not for scenario containing something, like "http" or "appsec"....
