If you’re trying to connect to a website and acquire the error: unable to get local issuer certificate,” this article will help you resolve the problem.
This Error is caused by an invalid or self-signed SSL certificate on the destination server.
This Error is caused by an invalid or self-signed SSL certificate on the destination server. This can be due to one of the following reasons:
- The SSL certificate has expired or still needs to be validated.
- The SSL certificate has been revoked.
- The browser does not trust the SSL certificate because it was issued by a CA (Certificate Authority) that isn’t trusted in your web browser’s settings. This can also happen if you are using a self-signed certificate and have not added it as authorized in your computer’s settings, which most people don’t do because they’re used to seeing warnings when visiting websites with untrusted certificates and thus think they don’t need to add them as trusted even though it would be safer if they did so!
The solution is to create a certificate you “trust” and use that as a Certificate Authority instead.
The solution is to create a certificate you “trust” and use that as a Certificate Authority instead. To do this, follow these steps:
Create a self-signed certificate authority (CA). This can be done on your own computer or on any server that has OpenSSL installed.
- Import your CA into your trust store under Windows or Mac OS X by double-clicking on it in Finder or Explorer, respectively, and navigating through Keychain Access/Keychain Settings -> Certificate Assistant -> Add Certificate…
First, make sure you have installed the ca-certificates package on your system.
First, make sure you have installed the ca-certificates package on your system. If you are using Ubuntu, it is already installed by default. If you are using CentOS, install the ca-certificates package by running the following command:
Sudo yum install ca-certificates
There are several reasons for the error “unable to get local issuer certificate.”
There are several reasons for the error “unable to get local issuer certificate.” One of them is that your SSL certificate has expired or needs validation. The other reason could be that the SSL certificate has been revoked, which means that someone has taken it offline because they believe it to have been compromised. Lastly, if you have installed an intermediate CA on your system and want to use its root CA as trusted root authority, then make sure all intermediate certificates are configured correctly for this trust chain from end-to-end (root CA -> intermediate CAs) to work perfectly with Internet Explorer 11+ on Windows 7+.
The SSL certificate has expired or is not yet valid.
If your Certificate has expired, you need to renew it. If the Certificate is not yet valid, or if the client cannot verify the validity of the current Certificate (e.g., because it’s self-signed), this Error may occur.
If your site uses an SSL certificate from a third-party provider and you’re seeing this error message on Google Chrome:
- Your web server might be configured incorrectly
- There could be an issue with how your server connects with Google Chrome
The SSL certificate has been revoked.
Revoked certificates are no longer valid and should not be used for any purpose. A revoked certificate can be caused by a security breach or change in the certification authority’s policy. In either case, getting an updated version of your website’s SSL certificate is important as soon as possible so that visitors can continue accessing your site securely.
The SSL certificate cannot be traced back to a trusted root authority.
This Error means that your web browser cannot verify the identity of the server you are connecting to and therefore considers it untrustworthy. If you see this error message, it’s likely because the server has either not installed an SSL certificate or an invalid one (for example, if its expiration date has passed). It could also mean that your computer doesn’t recognize any of the certificates in its list of trusted authorities; this can happen if there was some kind of change made recently on your computer that prevented it from being able to access those files anymore (for example, if they were moved or deleted).
Conclusion
If you are getting this Error, the first thing to do is check if the SSL certificate has expired. If it has yet to pass, you must find out why your server does not trust the Certificate. You can do this by contacting the company that issued your SSL certificate or asking them for help setting up a trust chain on their end so that other sites will also trust their certificates.
