Local Host Secure Connection Failed: SSL_ERROR_RX_RECORD_TOO_LONG

[Beacon24]

Everything is working properly on my heroku app, but now when I try to run the app on my localhost I get the following error in my browser window:

Secure Connection Failed

An error occurred during a connection to localhost:3000. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Any tips? I tried adding

if (app.get("env") === "production") {
   app.use(enforce.HTTPS({ trustProtoHeader: true }));
}

It did not work. Thanks!

I have now uninstalled sslify, and removed all the related lines of code, and I still can't run the app on localhost:3000! I'm not sure what to do.

Ok, figured it out, deleted all history and data, now it works.

Actually this only helped to allow me to use the localhost if I keep sslify uninstalled. When I tried to reinstall it, the same problem re-occurred.
