Firewalld Issues

Hi there,

CyberPanel is working correctly and the websites are working fine.
But whenever I reboot the VPS everything goes down.

So then, I stop the firewall from CLI and everything starts to work again.

The bottom line is whenever the firewall is up everything else is down.

Btw, I checked the firewall status from CLI and found the following errors:

ERROR: '/usr/sbin/ebtables-restore --noflush' failed: ebtables-restore v1.8.4 (nf_tables): 
    line 3: CHAIN_USER_DEL failed (Device or resource busy): chain PREROUTING_direct
    line 3: CHAIN_USER_DEL failed (Device or resource busy): chain POSTROUTING_direct
    line 3: CHAIN_USER_DEL failed (Device or resource busy): chain OUTPUT_direct
    line 7: CHAIN_USER_DEL failed (Device or resource busy): chain INPUT_direct

    line 7: CHAIN_USER_DEL failed (Device or resource busy): chain FORWARD_direct
3]: ERROR: COMMAND_FAILED: '/usr/sbin/ebtables-restore --noflush' failed: ebtables-restore v1.8.4 (nf_tables):

    line 7: CHAIN_USER_DEL failed (Device or resource busy): chain OUTPUT_direct
    line 7: CHAIN_USER_DEL failed (Device or resource busy): chain FORWARD_direct

What to do?

@josephgodwinke Any advice?

After restarting the Firewall the issue was resolved.

Command: $ sudo systemctl restart firewalld
