原因是因为配置 nacos 地址时, 在后面多加了一个 / 

报错的配置

留意 端口后的 / 

 nacos {
    application = "seata-server"
    serverAddr = "http://nacos.xxxxxxxx.com:8089/"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }

 

修正后:

留意 端口后的 / 

nacos {
    application = "seata-server"
    serverAddr = "http://nacos.puppy.com:8089"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
