Lambda Connection Issue

Question

we are getting an error Error while making REST call. Retry: 0, Message: IOException: Connection reset by peer, StackTrace: [java.net.http/jdk.internal.net.http.HttpClientImpl.send(Unknown Source), java.net.http/jdk.internal.net.http.HttpClientFacade.send(Unknown Source), but some time it is giving 200 status

Answer

Hi there

The error "Connection reset by peer" implies that the Downstream Service (the one that the Lambda Function is making a call to) has abruptly aborted the connection in the midst of the connection. The "java.io.IOException: Connection reset by peer" is also a type of IO exception.

It is a response from the server that it is not going to process this request. When the application establishes a TCP connection with a peer in the network, if that peer closes the connection on the far end, it will throw "java.io.IOException: Connection reset by peer in Java".

The most common reasons for the "java.io.IOException: Connection reset by peer in Java" error:

* The Downstream Service (the one that the Lambda Function is making a call to) has abruptly aborted the connection in the middle of a transaction.
* The Downstream Service was unavailable.
* There can be a problem with the PUT, POST, and GET requests.
 
The reasons are not limited to the above. Those errors need to be investigated from the perspective of the Downstream Service.
