If you are in a rush and cannot immediately set up a local CA, you can temporarily force your browser to accept the unverified localhost port.
Click anywhere on the error warning screen and type thisisunsafe directly on your keyboard. The page will instantly reload and bypass the restriction.

Navigate to your project directory and generate the certificate specifically for localhost : mkcert localhost Use code with caution. https localhost11501 verified
Troubleshooting "https://localhost:11501" SSL Connection Issues
For those who prefer a manual method or need granular control, it's possible to create a trusted certificate using the OpenSSL command-line tool.
When developing locally with modern web frameworks or microservices, you will often encounter URLs like https://localhost:11501 . If your application requires a "verified" HTTPS connection to function correctly—such as when testing secure cookies, OAuth authentication, or modern browser APIs—seeing SSL warning pages can stall your development entirely.
Navigate to your project directory and run this command to generate the specific certificates for localhost: mkcert localhost 127.0.0.1 ::1 Use code with caution. If you are in a rush and cannot
For a basic server, your setup will look like this: javascript
For a permanent, system-wide fix that tricks your browser into seeing https://localhost:11501 as natively valid and verified, use a tool called . It creates a local Certificate Authority (CA) on your machine. Step 1: Install mkcert macOS (via Homebrew): brew install mkcert nss Windows (via Chocolatey): choco install mkcert Linux (Ubuntu/Debian): sudo apt install mkcert Step 2: Install the Local CA
HTTPS stands for Hypertext Transfer Protocol Secure. It's an extension of the HTTP protocol but with an added layer of security. The "S" at the end signifies that the communication between your browser and the server is encrypted, ensuring that any data exchanged remains confidential and tamper-proof. This encryption is achieved through SSL/TLS certificates.
Point your local web server configuration (Node.js, Nginx, or Apache) running on port 11501 to use these newly generated .pem files. | Highly Recommended : The best
If you'd like, I can help you investigate further if you tell me:
Most local services use self-signed certificates. If your browser says "Verified," it means you (or the software installer) have added this specific certificate to your computer's Trusted Root Certification Authorities Browser Exceptions:
on a local unverified port unless you are entirely sure what background process is listening to port 11501.
| Method | Approach | Certificate "Verified" Status | Security & Recommendation | | :--- | :--- | :--- | :--- | | | Enables chrome://flags/#allow-insecure-localhost to ignore certificate errors. | Not Verified : Browser shows a warning, but bypasses it. | Not Recommended : Dangerous, as it trains you to ignore security warnings. | | Manual Self-Signed Certificate | Generate and sign your own certificate using OpenSSL , then manually add it to your OS trust store. | Verified : Browser shows as secure only on your machine . | Ok for Testing : Viable for experienced developers who need full control. | | The mkcert Tool | Automates creating and installing a locally-trusted CA and certificates in seconds. | Verified : Seamless, automatic trust across all browsers. | Highly Recommended : The best, most secure, and easiest method. |
