ALB is configured with idle-timeout - 5 minutes. I configured bi-di client with : keepAliveWithoutCalls(true).keepAliveTime(90, TimeUnit.SECONDS).keepAliveTimeout(10, TimeUnit.SECONDS) while server is configured with : permitKeepAliveWithoutCalls(true).permitKeepAliveTime(1, TimeUnit.MINUTES)
But I received INTERNAL: HTTP/2 error code: PROTOCOL_ERROR Received Rst Stream after exactly 5 minutes. Which looks like ALB has dropped the connection after 5 minutes. Any idea how we can keep idle connection alive ?
