I'm building an app to be hosted on heroku default service level like my_app.herokuapp.com which should open a websocket. Since domain is https:// I have to use wss:// in order to forward requests.
Problem is that the connection fails after 3 seconds
failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED
In the SSL-endpoint documentation page I can read
All default appname.herokuapp.com domains are already SSL-enabled and can be accessed by using https, for example, https://appname.herokuapp.com.
but in my_app detail page there is
SSL - Upgrade to paid dynos to configure Heroku SSL
I smell this could be the reason why the connection cannot be established but since these sentences seems contradictory I would like to understand better the matter.
I thought that since I'm using a subdomain the SSL is enabled but perhaps I need to upgrade to paid dyno in order to configurate it.
If this can be the deal my solution would be to upgrade to hobby license (7$/month) which ensures the
FREE SSL for custom Domains.
Am I missing something or this could be the reason?
