If your application fails to connect or verify on https://localhost:11501 , try these troubleshooting steps: Fix Certificate Warnings
A specific networking port. While default web traffic uses port 80 (HTTP) or 443 (HTTPS), custom applications, microservices, and development environments use unique ports like 11501 to avoid conflicts.
Accessing a "https://localhost:11501 verified" address that shows a "Not Secure" warning typically indicates a missing or self-signed SSL certificate, which can be bypassed in browsers by proceeding through the advanced settings or enabling "allow-insecure-localhost" in browser flags. For a permanent fix, the local certificate can be manually installed and trusted in the OS keychain, although this is only recommended for known, trusted services such as Citrix or Adobe applications. You can bypass the browser warning by selecting the "Advanced" option, or by configuring the browser to trust local certificates, to resolve the "Not Verified" message.

If you didn't manually configure this port yourself, it is likely being utilized by:
https.createServer(options, (req, res) => res.writeHead(200); res.end('Verified localhost:11501!\n'); ).listen(11501); If your application fails to connect or verify
Your certificate must explicitly include localhost . A certificate for myapp.local won’t verify for localhost:11501 . Use mkcert localhost 127.0.0.1 ::1 to cover all bases.
The SSL certificate must be issued by a that the browser or operating system recognizes (like Let's Encrypt, DigiCert, or GlobalSign). For a permanent fix, the local certificate can
The era of “HTTP is fine for local development” ended around 2018. Modern browsers increasingly lock features behind secure contexts. Here is why a specific verified HTTPS localhost matters:
Your operating system doesn't recognize the software developer as a trusted source yet. How to Verify and Fix the Connection
Because it uses https , the service requires an SSL certificate to encrypt the data.
Browser vendors are gradually tightening security.
