我们监控到，从2月11日晚上9点之后，调用微信的接口偶发会出现连接失败的情况，调用的接口地址是：https://api.weixin.qq.com/sns/component/jscode2session

有如下三种错误信息：

errcode:35，errmsg:"SSL connect error: Encountered end of file"

errcode:52，errmsg:"Server returned nothing (no headers, no data): Empty reply from server"

errcode:28，errmsg:"Timeout was reached: Operation timed out after 30001 milliseconds with 0 out of 0 bytes received"

这个能帮忙查看下是什么原因么？
