Unable to send logs from Filebeat to Logstash – EOF on TCP connection

Elastic Stack Logstash
1

I'm deploying Logstash on EKS and trying to expose it on port 443 using HAProxy Ingress. I'm using Filebeat to send logs to Logstash via the Beats protocol (Lumberjack), but I’m getting the following errors:

Failed to connect  to backoff(async(tcp://<my-domain>:443)): EOF
failed-to-publish-events-caused-by-lumberjack-protocol-error

Here is my Ingress configuration. Am I missing something, or is it wrong to expose Beats protocol via HTTP Ingress? test local Failed to connect to backoff(async(tcp://:443)): EOF","service.name":"filebeat","ecs.version":"1.6.0"} or failed-to-publish-events-caused-by-lumberjack-protocol-error my config

Yes, beats does not use HTTP, it is a proprietary protocol over TCP, so you need to use TCP.
