Description

We are using zuul gateway application which by default is using Apache http client 4.5.6 version. With this often we are facing connection reset issue for few of the transaction.  

And we are not sure why the httpclient is resetting the connection unexpectedly.

We are facing below error in all of our environment,

2020-02-03 16:54:20,904 [http-nio-8080-exec-1] DEBUG org.apache.http.wire [] http-outgoing-6 << "[read] I/O error: Connection reset"
