localhost is a hostname that resolves to the IPv4 address 127.0.0.1 or IPv6 ::1 . It represents your own computer. Traffic sent to localhost never leaves your machine. This is critical for security: no external entity can intercept the connection because the network stack loops the packets internally.

Are you trying to a local HTTPS server, or are you troubleshooting a specific error on this port?

The most specific application for port 11501 is software provided by IDT (a biotechnology company). If you are using their web-based tools for oligo analysis or ordering, the application may launch a local helper service on port 11501 to handle data processing or communication with lab instruments. The "verified" status indicates the local helper service is securely connected to your browser.

Some tools (like openssl with default settings) generate a self-signed certificate without a custom CA. Browsers will never trust that. Always use a local CA installation ( mkcert , dev-certs , Caddy ).

Verify that your hosts file correctly maps 11501 to the loopback address 127.0.0.1 . Restart the Service If the verification token expires or the service hangs:

This signifies that the data being transmitted between the client and the server is encrypted using TLS/SSL (Transport Layer Security). Unlike HTTP, HTTPS ensures that even if someone intercepts the network traffic, they cannot read the content. On localhost , this is often used to satisfy API requirements that demand secure connections (e.g., OAuth 2.0 redirects) or to test security configurations locally.

While bypassing or forcing verification on localhost:11501 is safe for local development, keep these rules in mind:

To ensure secure communication in your development environment, follow these best practices:

This generates two files: localhost.pem (the certificate) and localhost-key.pem (the private key). Configure your service running on port 11501 to use these files. Method 3: Manually Trust the Certificate via Browser/OS

In development environments, it's common to use HTTP (non-secure) to test and debug applications. However, this can lead to security risks, as sensitive data, such as login credentials, credit card numbers, or personal identifiable information (PII), can be intercepted or accessed by unauthorized parties. Moreover, modern web browsers have become increasingly strict about security, and many now display warnings or errors when encountering insecure connections.

This produces localhost+2.pem and localhost+2-key.pem . You then configure your server on port 11501 to use these files. Your browser will show “Verified” because the certificate chain traces back to a trusted root CA.

OAuth providers (Google, GitHub, Auth0) strictly validate redirect URIs. While they often allow localhost , some require . Port 11501 is memorable enough to be configured as a registered redirect URI for a local OAuth client. The “verified” HTTPS ensures the authorization code exchange happens over a secure channel.
