This is how I did it in Docker compose.
environment: - HOMEPAGE_ALLOWED_HOSTS=domain.com:12345 Host validation failed for: 192.168.1.5:3000. Hint: Set the HOMEPAGE_ALLOWED_HOSTS environment variable to allow requests from this host.
localhost:3000 and 127.0.0.1:3000 are always included, but you can add a domain or IP address to this list to allow that host such as HOMEPAGE_ALLOWED_HOSTS=gethomepage.dev,192.168.1.2:1234, etc.
