If you’re experiencing the NET:ERR_CERT_AUTHORITY_INVALID error, you may want to try clearing your cache, cookies, and history, which may solve the issue. If all else fails, try reloading the webpage, closing and reopening your browser. If you’re using a public network, you may encounter this error because it’s restricted by the network.

This error is related to your network connection, and can occur when your browser is not able to verify the validity of an SSL certificate. If you’re experiencing the error on a website that’s not secured by an SSL certificate, you may have an untrusted certificate authority, or you’ve signed the certificate yourself. Either way, there are a few easy ways to fix the issue.

If you’ve noticed that the certificate you’re using for your website is invalid, you need to contact the website’s owner to request a new certificate. If the certificate doesn’t work properly, the website might be impersonated by a hacker. To fix the problem, contact the website’s owner or webmaster to get it fixed. The site’s owner can help you resolve the issue.

The ‘ERR_CERT_AUTHORITY_INVALID’ error is caused by a certificate that’s expired. The SSL encryption used by the website protects network connections and web page operations. If the certificate expires, the problem is most likely to be resolved by renewing the certificate or installing a new one. If the above steps didn’t fix the problem, you may need to troubleshoot your computer.
