How do I fix a 401 Unauthorized error in Vast.ai?

A 401 error typically indicates an invalid or missing API key. Verify your configuration with 'vastai show user' or regenerate your key at cloud.vast.ai.

What should I do if I get a CUDA not available error?

This is usually caused by a driver mismatch. Ensure you are using NVIDIA-provided base images that match the host's maximum supported CUDA version, which you can check via 'vastai show instance ID --raw'.

Why is my Vast.ai instance stuck in the loading state?

The 'loading' status means the Docker image is downloading. Large images can take 5-10 minutes. If it persists, the host may have slow internet or the image size might be excessive.

How can I resolve SSH Permission Denied errors?

Ensure your SSH public key is correctly uploaded to the Vast.ai account settings and use '-o StrictHostKeyChecking=no' for ephemeral instances to bypass host key verification issues.
