Wazuh agents not connecting via subdomain (multi-customer setup)

[Sumit Kumawat]

Hello,

I have deployed Wazuh OVA (https://packages.wazuh.com/4.x/vm/wazuh-4.12.0.ova) on my VMware in a local network. I want to provide it to multiple customers:

• Customer 1 → 192.168.0.11 → customer1.example.com

• Customer 2 → 192.168.0.12 → customer2.example.com

• Customer 3 → 192.168.0.13 → customer3.example.com

Wazuh dashboard (ports 80/443) functions properly with the proxied DNS, but agents on all platforms are unable to connect to their respective subdomains.

Can anyone guide me on how to properly set up agents for multi-customer access?

Thanks in advance!

To clarify the problem, could you tell me what the architecture you're proposing is like?
- Have you installed an agent on each of the customer<n>.example.com domains/IPs?
- Do you want to connect these agents to the OVA, which is on another domain/IP?
- How have you configured the agents?

Make sure to enter the manager's host or domain on each agent. And, very importantly, for the agents to report correctly to the manager, you must have connectivity through TCP ports 1515 and 1514, which are the ones the agent uses to enroll and communicate with Wazuh Manager. I'm sharing this section of the documentation for troubleshooting connectivity: https://documentation.wazuh.com/current/user-manual/agent/agent-enrollment/troubleshooting.html.
You can also check if you have any port blocking at the firewall level.

Thanks for the help. 

My agents are now able to connect to my self-hosted dashboard successfully. 

We can close the thread.
