I'm using SpringBoot with JDK 11. This application is deployed on a container (AWS).
Into my REST Controllers I need to call internally external REST api services (using TLS 1.2)
I'm using java.net.http.HttpClient for this.
httpClient = HttpClient.newHttpClient();
(I'm using only one httpClient for all requests)
Sometimes (randomically) these requests fail. Into my logs I see as cause of this problem:
Connection reset by peer
This is strange for me. As already explained, this error does not happen systematically.
I analysed my code but I don't notice anything wrong.
Any suggestion?
Is the HttpClient initialization correct?
Is possible that the cause it's related to my code or from the external services?
Any suggestions are welcome.
