Net::err_cert_common_name_invalid is an error code displayed in a web browser when the browser is unable to verify the identity of a website due to a mismatch between the domain name and the Common Name (CN) in the SSL/TLS certificate. This error can be caused by a variety of factors, and it is important to understand the underlying cause in order to successfully troubleshoot the issue.
Understanding net::err_cert_common_name_invalid
Net::err_cert_common_name_invalid is an error code displayed in web browsers, such as Chrome and Firefox, when the browser is unable to verify the identity of a website due to a mismatch between the domain name and the Common Name (CN) in the SSL/TLS certificate. This error usually occurs when the domain name does not exactly match the CN in the certificate, for example if the domain name is www.example.com and the CN in the certificate is example.com.
The CN is a critical component of an SSL/TLS certificate and is used to verify the domain name of the website being visited. If the CN does not match the domain name, the browser will display the net::err_cert_common_name_invalid error.
Troubleshooting net::err_cert_common_name_invalid
- Check the domain name: The first step in troubleshooting this issue is to ensure that the domain name is spelled correctly. If the domain name in the URL bar is different from the CN in the certificate, the browser will display the net::err_cert_common_name_invalid error.
- Check the SSL/TLS certificate: The next step is to ensure that the SSL/TLS certificate is valid and up-to-date. If the certificate is expired or invalid, the browser will display the net::err_cert_common_name_invalid error.
- Check the DNS settings: If the domain name and certificate are both valid, it is important to check the DNS settings. If the DNS settings are incorrect or out of date, the browser will display the net::err_cert_common_name_invalid error.
