NOAUTH Authentication Required - Upstash Documentation

Symptom

The client can not connect to the database throwing an exception similar to:

[ioredis] Unhandled error event:
ReplyError: NOAUTH Authentication required

Diagnosis

The server does not let you connect because the password is missing in your connection parameters.

Solution

Check your connection parameters and ensure they contain the password. If you are using ioredis (Redis client) with a Redis URL, check the URL format. ioredis requires a colon before the password. The format for IORedis - TLS enabled

rediss://:YOUR_PASSWORD@YOUR_ENDPOINT:YOUR_PORT

The format for IORedis - TLS disabled

redis://:YOUR_PASSWORD@YOUR_ENDPOINT:YOUR_PORT

You can copy the correct client configuration from Upstash console clicking on Redis Connect button.
