  }

I only do the configuration, in addition to no additional control in the code

↓ code vew

Further technical details

• Use Windows 😗
• TargetFramework：net5.0 😍
• PackageReference：Yarp.ReverseProxy 1.1.2 😍

😥 In addition, my English level and professional technology level is low, I want to claim the company encountered when using yarp has problem, if you can, can help analyze the problem of what might be the reason

[NingLiu1998]

I refer to the document： → https://microsoft.github.io/reverse-proxy/index.html

The translator I use is：youdao

[NingLiu1998]

There is a problem to find the cause, I filled in the configuration is https://localhost:8661 in fact, my api is http://localhost:8661, so it will cause SSL errors

After this problem is solved, it will still exist

The request is for the same address, and the following problems will appear randomly on each refresh

This problem

Sometimes error：

Sometimes success：

。。i find #2175 maybe is HealthCheck no address √
