Root Cause

The JWT token's claims (e.g., audience, issuer, or expiration) do not match the server's expected values, often due to clock skew or misconfiguration.

generic

中文

JWT 令牌的声明(如受众、颁发者或过期时间)与服务器期望值不匹配,通常由时钟偏差或配置错误导致。

Workarounds

  1. 75% success Synchronize server and client clocks using NTP, then retry the request. For example, on Linux: `sudo ntpdate pool.ntp.org` or enable `systemd-timesyncd`.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Token regeneration does not fix clock skew or misconfigured audience/issuer values; the new token will still be rejected.

  2. 90% fail

    Disabling validation exposes the API to unauthorized access and token forgery.

  3. 80% fail

    Changing the payload invalidates the signature, leading to a signature verification failure.
