Webpack log errors "net::ERR_SSL_PROTOCOL_ERROR" by calling sockjs-node/info

Question

on front I use react on back .net core 3.1

on client I use webpack that is runned on localhost:8080

in Startup.cs I use proxyToSpa

 applicationBuilder.UseSpa(spa =>
                {
                    spa.UseProxyToSpaDevelopmentServer("http://localhost:8080/");
                });

on HTTP works as expected without any errors but on HTTPS I saw a lot of console errors and failed requests in Network there is failed requests for (sockjs-node/info?t=...) with error net::ERR_SSL_PROTOCOL_ERROR

Is there any options to configure webpack or .net core project to avoid these error logs on HTTPS?

Answer 1

This might be the issue, it worked for me

If you ever visited the https version of a website (whether it resolved or not), Google Chrome might repeatedly send you to that version

Answer 2

https://webpack.js.org/configuration/dev-server/#devserverdisablehostcheck

using cli

webpack-dev-server --disable-host-check

or in webpack config

devServer: {
        disableHostCheck: true
    }
