Error in webhook: "http: TLS handshake error from 10.1.2.3:12345: EOF" is still an issue

[ArieLevs]

Describe the bug

argo events webhook outputs TLS handshake errors

Related helm chart

argo-events

Helm chart version

2.4.8

To Reproduce

set webhook.enabled: true.
change port to webhook.port: 80.
Deploy argo events chart 2.4.8

Expected behavior

no errors should return, or alternatively proper documentation for setting certificates for webhook component

Screenshots

No response

Additional context

issue #2137 never resolved,
although chart 2.4.8 (argo-rollouts-2.37.7...argo-events-2.4.8) seem to allow now the ability to set a different port other than 443, TLS related errors still returned

argoproj/argo-events#2915 also suggest a port change, but it has no effect
