The context of 2021 is also telling. Around this time, the HTTPS-everywhere movement was in full swing. Major browsers, including Chrome, were moving toward stricter security postures, increasingly flagging non-HTTPS sites as "Not Secure." This pressure accelerated the adoption of HTTPS for all web traffic, including in local development environments.
https.createServer(options, app).listen(11501, () => console.log('Secure server running on https://localhost:11501'); );
So seeing https://localhost:11501 in a 2021 context likely means you were on the cutting edge of local secure development – or just following a guide that picked a quirky port. https localhost11501 2021
To understand the context, we must break the string down into its technical components:
: Open the Control Panel, go to Internet Options , select the Content tab, and click Clear SSL State . The context of 2021 is also telling
If your server uses http://localhost:11501 , but you typed https:// , the browser will fail because no SSL handshake occurs.
If a developer in 2021 configured a project to run HTTPS on port 11501, the command might have been: If a developer in 2021 configured a project
Use http://localhost:11501/2021 instead, or configure SSL for your local server.
Port 11501 is not a standard well-known port (like 80 for HTTP or 443 for HTTPS). In 2021, many developers chose high-numbered ports to avoid conflicts with system services.
Using https with localhost can be problematic. While self-signed certificates are possible, browsers often display security warnings. Here's why you might see this:
