I'm seeking assistance with connecting a Cribl Stream worker (running on a GCP VM) to our Cribl Cloud Leader. We are encountering a persistent connection handshake timeout error, despite extensive troubleshooting that indicates the network path through our corporate proxy is otherwise functional.
Environment Details:
- Cribl Version: Latest (installed via
install-worker.shscript) - Worker OS: Ubuntu (GCP VM)

- Connectivity Requirement: All outbound internet traffic from the VM must pass through a corporate HTTP/HTTPS proxy
Are there any known issues or specific configurations required for Cribl workers connecting via corporate HTTP/HTTPS proxies,
