haproxy + spring boot writeAddress(..) failed: Connection reset by peer

I'm running HAproxy with backend Spring Boot Rest controllers. My spring log shows constant errors that look like the following:

[reactor-http-epoll-26] ERROR o.s.w.s.a.HttpWebHandlerAdapter - [9df8bfcf] Error [io.netty.channel.unix.Errors$NativeIoException: writeAddress(..) failed: Connection reset by peer] for HTTP GET "/api/v1/status", but ServerHttpResponse already committed (200 OK)

HAproxy performs an HTTP check on the url /api/v1/status. What would be the reason that I'm getting these errors?

HAproxy is doing GET request, reads http response code and closing connection. Boot is trying to send remaining parts (http headers and some json payload) but connection is already closed.

Just replace GET with OPTIONS in the line:

option httpchk GET /api/v1/status HTTP/1.0
