I’ve installed CrowdSec and the iptables bouncer on CentOS 8 per the instructions on the site, but it doesn’t appear to be working. I’ve checked that selinux is off, and that nothing else is using port 8080 or 6060. After rebooting, the CrowdSec service is in the failed state:
# systemctl status crowdsec ● crowdsec.service - Crowdsec agent Loaded: loaded (/usr/lib/systemd/system/crowdsec.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2021-09-21 03:41:47 PDT; 53s ago Process: 1529 ExecStart=/usr/bin/crowdsec -c /etc/crowdsec/config.yaml (code=exited, status=1/FAILURE) Process: 1098 ExecStartPre=/usr//bin/crowdsec -c /etc/crowdsec/config.yaml -t (code=exited, status=0/SUCCESS) Main PID: 1529 (code=exited, status=1/FAILURE) Sep 21 03:41:13 support.calibercpas.com systemd: Starting Crowdsec agent...

Running systemctl restart crowdsec gets it running without any immediate errors thrown, but after a few minutes it re-enters the error state with the above message. Searching for this error seems to be more related to Docker installs, of which this is not.
