Error in Postman: Error: write EPROTO 8768:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:

Question

During request GET in Postman (https://localhost:9001/test) I've received an error:

Error: write EPROTO 8768:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\users\administrator\buildkite-agent\builds\pm-electron\postman\electron-release\vendor\node\deps\openssl\openssl\ssl\record\ssl3_record.c:252:

Warning: This request did not get sent completely and might not have all the required system headers.

Postman Configuration:

SSL certificate verification is disabled;
Proxy configuration - Default Proxy Configuration and Proxy configurations for sending requests are disabled;
Request timeout in ms - 0.

This error message typically happens if you try HTTPS communication on something that is not HTTPS but more HTTP (that is not speaking TLS at all). Make sure your endpoint is HTTPS. — Patrick Mevzek, May 20 '20 at 15:42

For Localhost we don't really need https, please try with http://localhost:9001/test

NOT

check that you are using the HTTP protocol not HTTPS to send requests to the server:

example

export const config = {
    baseUrl: "http://localhost:4000"
}

const transporter = nodemailer.createTransport({
    host:'smtp.gmail.com',
    port:587,
    secure:false,
    requireTLC:true,
    auth: {
        user:'youmail@gmail.com',
        pass:'youpass'
    }
}

Notice that secure: is false.

The error occurs when secure: is true.

the reason was in an incorrect link. In the controller I have used

@RequestMapping(value="/{baseSiteId}/test")

And this {baseSiteId} was not what I expected.
