Error message

Trying to use ENTERPRISE BlockedUserYou must be a LiteLLM Enterprise user to use this feature. If you have a license please set `LITELLM_LICENSE` in your env. Get a 7 day trial key here: https://www.litellm.ai/enterprise#trial.

What it means

The 'blocked_user_check' callback found the enterprise module (the import succeeded), but the license check failed: premium_user is not True. The proxy appends CommonProxyErrors.not_premium_user to 'Trying to use ENTERPRISE BlockedUser' and stops config loading. The license state is read from LITELLM_LICENSE at startup.

Solutions

1. Set a valid LITELLM_LICENSE env var on the proxy process and restart it.
2. Or remove 'blocked_user_check' from the callbacks list.
3. Check startup logs for the license verification call to confirm the key was sent and accepted.

Example fix

# before
docker run litellm/litellm-enterprise --config config.yaml

# after
docker run -e LITELLM_LICENSE="sk-..." litellm/litellm-enterprise --config config.yaml

import os

def startup_env_ok(callbacks: list[str]) -> list[str]:
    errs = []
    if "blocked_user_check" in callbacks and not os.environ.get("LITELLM_LICENSE"):
        errs.append("LITELLM_LICENSE missing for blocked_user_check")
    return errs

try:
    start_proxy(cfg)
except Exception as e:
    if "ENTERPRISE BlockedUser" in str(e):
        log.error("set LITELLM_LICENSE or remove blocked_user_check")
        raise SystemExit(2)
    raise

When it happens

Trigger: The proxy runs on the enterprise Docker image with callbacks: ['blocked_user_check'], but LITELLM_LICENSE is unset, expired, or rejected by the license check.

Common situations: The Docker image is correct but the -e LITELLM_LICENSE flag was dropped from the run command. The trial ended. The license key was rotated and the old one is still in the deployment manifest.
