Wazuh Dashboard --port override not working: 443 Conflict. Installation failed

[Jeeva DotNet]

Wazuh version
v.4.5.2
Wazuh Assistant Installer
Ubuntu 20.04 LTS

Issue
Installing the Wazuh Dashboard using the assistant installer. I'm running my reverse proxy on 443 for wazuh and other services and want to change the port during the installation process.

bash wazuh-install.sh --wazuh-dashboard dashboard -p 5601 

with -p as per the documentation.

Getting the error that the installation has failed.

Hi Jeeva DotNet,

Hope you are doing well. Thank you for using Wazuh.

I guess you are installing the Wazuh dashboard using the assistant process.

Please allow me sometimes to recreate this issue in my lab and come up with findings.

Hi Jeeva,

I have looked into your issue and found some interesting facts about wazuh-dashboard installation using the port option. Even if you are using a port other than 443, for some reason Wazuh dashboard needs 443 port during the installation process. So I have tried to stop my nginx server that was running on 443 port and the dashboard installation worked. After installation, I checked the dashboard was running on the 5061 port. Also, I have restarted the Nginx that was running on the 443 port and it is not conflicting with wazuh-dashbaord. You can try this method if possible. I will let you know if I find any alternative.

I hope this helps. Please let me know if you need any further help.

Regards
