When installing DeployR Community Edition, you may want to expose it to the internet or place it behind a firewall. In these scenarios, the internal IP address of the server will not match the external IP address—which is completely expected.

However, DeployR Community Edition has a requirement:
for security and operational reasons, the FQDN (Fully Qualified Domain Name) must match the server’s internal IP address during installation.

If this requirement is not met, the installation will not allow you to continue.

How to Fix the Issue

Fortunately, the solution is straightforward.

1. Open Notepad as an Administrator
2. Navigate to: C:\Windows\System32\drivers\etc\hosts
3. Add a new entry mapping:
   • The internal IP address of the server
   • To the external FQDN

Example:

192.168.1.10   deployr0.yourdomain.com

Save the file and proceed with the installation again. This ensures that the FQDN resolves correctly during setup, allowing the installation to complete successfully.
