Applicability

Splunk Enterprise Splunk Cloud Splunk AI Assistant

Description

  • When activating the Splunk AI Assistant app, the setup page displays the error “Cannot connect to Splunk Cloud. Please check your Internet Connection / Firewall / Proxy Configurations and try again” after submitting the activation token. This error indicates that the Splunk Enterprise instance is unable to reach Splunk Cloud Services (SCS). As a result, the activation process cannot complete successfully.
  • This is typically seen in environments with restricted outbound connectivity, firewall blocks, or required proxy configurations. As a result, the Splunk AI Assistant activation process is unsuccessful.


Investigation

  • Verify outbound internet connectivity from the Splunk host using.
  • Check firewall configurations to confirm that outbound HTTPS traffic was allowed to Splunk Cloud Services (SCS) endpoints and that no security rules were blocking the connections.
  • Validate whether a proxy was required in the environment and reviewed the proxy settings configured in Splunk for accuracy (hostname, port, protocol, and credentials).
  • Test connectivity to Splunk Cloud Services through the configured proxy to confirm proxy reachability and functionality.
  • Review Splunk logs for connection failures, timeout errors, or SSL-related messages to confirm the issue was caused by network or connectivity restrictions rather than an application defect.

Resolution

  • Confirm that the Splunk Enterprise instance has outbound internet connectivity and can reach external services.
  • Update firewall rules to allow outbound HTTPS traffic to Splunk Cloud Services (SCS) endpoints on port 443.
  • Configure proxy settings correctly in Splunk if a proxy is required, ensuring the proxy hostname, port, protocol, and credentials are accurate.Verify that the proxy server is running and reachable from the Splunk environment.
  • Retry the Splunk AI Assistant activation after confirming connectivity, firewall, and proxy configurations are correct.
