I just created a tiny test app with vue cli, so without adding anything, apart from what the empty vue-cli scaffolding brings.

Does the same output is generated if you use non-secure protocol (http) ?

marcoippolito · 2020-01-31T19:02:11Z

@PS-Ddevil I didn't directly create a SockJS object myself. I just created a tiny test app with vue cli, so without adding anything, apart from what the empty vue-cli scaffolding brings.
