NVIDIA NIM GLM 5.3 inference requests time out

I can successfully call GET ``https://integrate.api.nvidia.com/v1/models, but POST https://integrate.api.nvidia.com/v1/chat/completions consistently times out with curl: (28) Operation timed out and HTTP status 000.

Model: z-ai/glm-5.3

Environment: Kali Linux running under WSL.

Please check whether my account has the required hosted-inference entitlement and whether there is a service-side issue affecting chat completions.

I have not included my API key for security reasons.
