I have frontend on Netlify and my socket.io backend on another server. The problem is that when socket.io creates a polling request the connection is not made (status: (blocked:mixed-content)). When I’m manually trying GET from browser http://domain:port/socket.io/?EIO=3&transport=polling then I get a response. And when I’m testing with socket.io tools eg. Firecamp I’m also able to connect.
Is this something specific to netlify that socket.io connection is not allowed or this is still a thing on my end?
