@StefanHoutzager I forgot but I also did not take enough into consideration so far the point in REST over WebSockets instead of HTTP about the corporate environments compatibility with websockets.
I will move to wss://
(it seems that using SSL in phoenix should make websockets also use SSL) and hopefully I won’t meet a customer using proxies with fake root certificates (I actually worked some years ago in a company using this, urgh…). Thanks for the link.
