node.js/express: crbug/1173575, non-JS module files deprecated. ... ERR_SSL_PROTOCOL_ERROR

 

>PROBLEM

Attempt to access the site returns the following error messages:

- On browser console:

crbug/1173575, non-JS module files deprecated.

- On browser page:

ERR_SSL_PROTOCOL_ERROR

Não foi possível estabelecer uma conexão segura com este site

Not possible to establish a secure connection with the site

>SOLUTION

Probably you've tried to access the site using https where it should be http.

Ex.:

- wrong:

https://localhost:3000

- because it uses the http protocol service, so:

http://localhost:3000
