The log message indicates a failure to download the file fraser-6.10-stable_build_release.tar.xz from a web server, resulting in anHTTP 404 Not Founderror when attempting to connect to the server overport 80. The error suggests that the Microservices Platform (MSP) is attempting to access a resource via HTTP (port 80), but the connection fails, either because the server is not reachable, the resource is not available, or the port is blocked.

TheNutanix Unified Storage Administration (NUSA)course discusses the Microservices Platform (MSP) as a component that supports containerized services in Nutanix environments, often requiring access to external repositories for downloading build artifacts, such as those hosted on AWS ECR (Elastic Container Registry). The course notes that “MSP services may require outbound network access to download container images or configuration files, typically over HTTP (port 80) or HTTPS (port 443), depending on the repository configuration.”

In this case, the log explicitly shows the attempt to useHTTP (port 80)to access the URL http://x.x.x.x/..., indicating that MSP is configured to use HTTP for this operation. The HTTP 404 Not Founderror suggests that either the file does not exist at the specified URL, the server is not responding, or network connectivity issues (e.g., firewall rules blocking port 80) are preventing MSP from reaching the web server. Since the error occurs during the connection attempt over port 80, the most likely cause is thatMSP needs to reach the web server over port 80, and this connectivity is not properly configured or is blocked.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide emphasizes troubleshooting network connectivity for Nutanix services, stating, “Administrators must ensure that required ports, such as 80 for HTTP or 443 for HTTPS, are open for services like MSP to access external resources.” The guide also recommends checking firewall rules, proxy settings, and network routes when encountering connectivity errors like HTTP 404.

The provided search results further support this analysis. For example, troubleshooting connectivity issues in Nutanix environments often involves verifying port access, as seen in discussions about Pulse and other services requiring HTTP (port 80) or HTTPS (port 443) connectivity to external servers (e.g., nsc01.nutanix.net or insights.nutanix.com). While the specific issue in the log is related to MSP, the principle of ensuring proper port access applies.

The other options are incorrect:

Prism Central needs to reach the web server over port 443: The log indicates that MSP, not Prism Central, is attempting the connection, and it uses HTTP (port 80), not HTTPS (port 443).

MSP needs to reach the web server over port 443: The log clearly shows the connection attempt over HTTP (port 80), not HTTPS (port 443).

Prism Central needs to reach the web server over port 80: The log references MSP, not Prism Central, as the component attempting the download.

To resolve this issue, the administrator should:

Verify that the web server at x.x.x.x is reachable and the file exists at the specified URL.

Ensure that outbound traffic from the MSP service to the web server over port 80 is allowed by checking firewall rules, proxy settings, and network configurations.

If the server requires HTTPS, update the MSP configuration to use port 443 instead of port 80, but the log suggests port 80 is expected.
