请求后端服务时404

[dylan8888]

遇到一个很奇怪的现象，暂时无法确定哪个环境出问题。就是后端服务和apisix都是部署在k8s上，前端调用apisix网关接口时，偶尔返回404。不知道大家有没有遇到过，然后大概是哪个环节的问题？

1. config show_upstream_status_in_response_header as true, ref: https://github.com/apache/apisix/blob/master/docs/zh/latest/debug-function.md
2. What version of APISIX is being used?
3. Whether to handle a mix of http and https traffic?

we use docker image is apache/apisix:2.14.1-alpine。and just http protocol

You can find the access log corresponding to the 404 response and see if it came from upstream.
