2020/01/03 19：30~20：30期间，我们小程序调用发送订阅消息接口报错：

{"errcode":45009,"errmsg":"reach max api daily quota limit hints: [OjbaFawhE-9nqydA!]"} PostJson:{"touser":"oY_OH5ML7UCajfACfnvmxX3lCgqI","template_id":"DLtJJZHShRXU1qXqAJXttG2Yy86yJpGSv6fbPYftyZ4","page":"/pages/person/orderDetail?orderGuid=47d1ccca-4054-4a64-baf9-556ddec104a9&orderType=退还押金","data":{"character_string2":{"value":"RC202001030000109"},"character_string1":{"value":"2020-01-03 19:30:15"},"thing14":{"value":"幻充共享充电宝"},"thing12":{"value":"充电宝押金退还成功"},"thing13":{"value":"成功退还押金100.00元"}}}

请问，订阅消息接口是有日上限么，但是我们只有这1个小时调用这个接口报错，之前或之后调用又没有报错，应该不是超过日上限的原因吧，麻烦帮忙查看下是什么原因
