Hello Parvaj
The error message indicates that wazuh-authd is trying to run and use the 1515 port but, this port is used by another process, maybe from other software, maybe a previous auth zombie process. I would recommend you:
1. Stop the Wazuh manager by systemctl stop wazuh-manager
2. Check if exist any wazuh daemon with ps -xa | grep wazuh. If exist, kill the process with kill -9 <PID>, where <PID> is the PID of the process you find inps` previous command.
3. Check if other software is using 1515 by netstat -tunap | grep 1515. If so, please stop the software, or the process.
4. Start the Wazuh manager again: systemctl start wazuh-manager
Hope it helps
