Not able to use https protocol getting net::ERR_CONNECTION_REFUSED in browser

[vasanth-kumar-m-y]

Hi
I am using symfony 4.4 (legacy, not flex) inside an vagrant machine, which is setup to use Apache web server and have self signed ssl certificates to run it over https. Same goes to client side an angular application inside vagrant machine with self signed ssl on https.

Have installed mercure bundle for real time data push to client application. Have downloaded the latest static binary and placed the binary hub at the root of the project. Everything works fine with http protocol (http://my.api.local:3000/.well-known/mercure) but when i change this to https protocol (https://my.api.local:3000/.well-known/mercure) getting net::ERR_CONNECTION_REFUSED error while subscribing for updates from browser.

Starting the mercure using command: (using 0.0.0.0 as its inside vagrant to listen to all ips)

`MERCURE_PUBLISHER_JWT_KEY='!someSecretKey!' MERCURE_SUBSCRIBER_JWT_KEY='!someSecretKey!' ./mercure run --config Caddyfile.dev
`

Set env variables in parameter.yaml:

env(MERCURE_URL): https://my.api.local:3000/.well-known/mercure
env(MERCURE_PUBLISHER_JWT_KEY): '!someSecretKey!'
env(MERCURE_SUBSCRIBER_JWT_KEY): '!someSecretKey!'
env(MERCURE_JWT_TOKEN): 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtZXJjdXJlIjp7InB1Ymxpc2giOlsiKiJdfX0.nFIuQOrDGSudHFiod2QeVjlvpo88tjKioZdGTArIETY'

Set up in config.yaml:

mercure:
    enable_profiler: '%kernel.debug%'
    hubs:
        default:
            url: '%env(MERCURE_URL)%'
            jwt: '%env(MERCURE_JWT_TOKEN)%'
