PoW验证数据无效

Error message

PoW验证数据无效

What it means

Validation error in solveRemotePowChallenge (plugin/gying/gying.go:1698): the challenge JSON decoded but required fields are missing/invalid (N or X empty, or T <= 0), so computing the proof-of-work is impossible. Indicates the site returned a structurally valid but incomplete challenge.

Solutions

1. 打印 challenge 原始字段定位缺失项
2. 确认站点 PoW 协议字段名未变更
3. 对 T<=0 场景检查服务端时间参数含义
