Each JWT token is invalid error includes a UUID that appears in brackets immediately after the error (for example, JWT token is invalid. [0ce9eb56-821d-4ca9-a774-04ae89a0cf5a]). You should provide the UUID of the error to a Snowflake administrator so they can obtain more information about the error. Unlock the problem to an “invalid secret key” error that can be received when setting up or changing a time-based one-time password (TOTP). One of the most common causes of MFA code invalid errors is a time sync problem. Since TOTP codes rely on time, even a slight difference between your device and the server can cause the code error. After syncing, try logging in again with the new code. If you’re seeing “invalid TOTP code” errors, one of the five mistakes below is almost certainly the cause. Each section explains the symptom, root cause, and a concrete fix—with Python and JavaScript code examples. Learn the common causes of the “too many login attempts” issue and how it affects users. Identify the error messages and symptoms associated with this problem on different platforms. Discover quick fixes to try, such as clearing cache, restarting devices, and using alternative browsers. Error code 394304 occurs when Snowflake cannot interpret a value as a valid number during data operations. By cleansing your data, adjusting loading parameters, and ensuring data types are consistent, you can resolve this error and facilitate smooth data loading and processing in Snowflake. Note: A TOTP code may be valid before and after it becomes visible. However, if the time on both devices (your device and the TOTP servers) is not synchronized, no code will be valid. To fix this issue, make sure your device is synced to the correct time by following these steps: Once you generate the key pair, you map the public key with the user record on the Snowflake. While the connection is initiated by the client, the private key has to be present in the connection string. You can now generate one-time passcodes (OTPs) that users can use as their second factor of authentication when signing in to Snowflake with multi-factor authentication (MFA). When generation, delivery, and validation timing do not align, users may enter a correct code that the system no longer accepts, resulting in a failed verification attempt.
