XAMPP Server Certificate Does Not Include an ID Which Matches the Server Name

When using XAMPP, a popular open-source software that provides a local web server environment, you may encounter an error message stating that the server certificate does not include an ID which matches the server name. This error occurs when trying to access your local website using HTTPS, indicating a mismatch between the server name and the certificate provided by XAMPP.

This error is typically caused when the server name specified in the web browser does not match the Common Name (CN) or Subject Alternative Name (SAN) in the server certificate. The CN or SAN is used to identify the server and establish a secure connection.

To resolve this issue, you have a few options:

1. Update the server name: Ensure that the server name used in the web browser matches the CN or SAN specified in the server certificate. You can do this by modifying the server name in the browser’s address bar or updating the server configuration to reflect the correct name.

2. Generate a new self-signed certificate: XAMPP provides a utility called OpenSSL that allows you to generate a self-signed certificate with the correct server name. You can run the following command in the XAMPP shell to generate a new certificate:
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout server.key -out server.crt
This command will generate a new self-signed certificate (server.crt) and private key (server.key) valid for 365 days. Make sure to specify the correct server name when prompted during the certificate generation process.

3. Obtain a trusted certificate: If you plan to use your local website on a public network or for production purposes, it is recommended to obtain a trusted certificate from a trusted certificate authority (CA). Trusted certificates ensure that your website is secure and trusted by web browsers without any error messages. Various CAs offer affordable or free certificates for development purposes.


Q: Why am I seeing this error message in my browser?
A: This error occurs when the server name specified in your browser does not match the server name defined in the server certificate. The mismatch prevents a secure connection from being established.

Q: Can I ignore this error and continue browsing?
A: While it is technically possible to ignore this error and proceed, it is not recommended. Ignoring certificate errors can expose you to security risks, such as data interception or manipulation.

Q: Can I use a trusted certificate for my local website?
A: Yes, you can use a trusted certificate for your local website. However, trusted certificates are typically used for production websites and may involve additional costs. For development or testing purposes, self-signed certificates are commonly used.

Q: How often do I need to regenerate my self-signed certificate?
A: Self-signed certificates have an expiration date, typically set for a year. You should regenerate the certificate before it expires to ensure uninterrupted access to your local website.

Q: Will this error occur when deploying my website on a live server?
A: This error is specific to local development environments like XAMPP. When deploying your website on a live server with a valid and trusted certificate, this error should not occur as long as the server name matches the certificate’s CN or SAN.
