HashiCorp Boundary insights

Users experience 'No workers are available to handle this session, or all have been filtered' errors during session authorization, indicating worker connectivity or configuration issues that prevent session establishment.

Multi-hop sessions fail with 'No ingress workers with valid next-hop paths could be found' error in high availability controller deployments, caused by controllers lacking unique names in their configuration.

Session proxy connections experience elevated latency between TLS establishment and first HTTP header response, indicating worker proxy performance issues that impact user experience.

API rate limiting quotas approach storage capacity limits, risking throttling of legitimate requests and impacting controller availability for authentication and session authorization operations.

Worker proxy connections experience bandwidth constraints as sent/received byte totals approach network interface limits, causing session quality degradation and potential connection failures.

Elevated latency in controller cluster gRPC communications signals control plane stress, potentially impacting worker registration, session authorization, and multi-controller coordination in HA deployments.

High volumes of session connections close with 'unknown' or 'system error' reasons, indicating unhandled failure scenarios that impact observability and may signal underlying infrastructure issues.
