Filebeat to Logstash via reverse proxy

Elastic Stack Beats
1

Hi All,
I am new here. We have configured filebeat to logstash via SSL in our test environment. In our production environment, we are planning for an architecture similar to below:

Filebeat > Secure Apache based reverse proxy > Logstash > ES > Kibana

We are planning to use version 7.3.x.
I have few queries here,

  1. When I read through few posts, I find communication through http based reverse proxy is not feasible between filebeat and logstash. Only SOCKS5 proxy is allowed. Is this same for 7.3.x as well?
  2. Apart from SSL, does 7.3.x filebeat supports user authenication to logstash, similar to elasticsearch?

Note - We are not using X-Pack as of now.

Thanks
Jai.

Update to above post -
I have apache 2.4 reverse proxy between Filebeat and logstash. Disabled SSL now. I get below error in filebeat log
