The browser still shows the old certificate after a new certificate is installed
This guide provides standardized resolution solutions verified by Certificate Authorities (CAs) for frequent security alerts that occur after certificate deployment.
The browser still displays the old certificate after installing the new certificate.
Possible causes:
- The certificate was replaced in the wrong location. You need to check the configuration file and verify that the correct new certificate path is entered in the configuration file.
- The website uses devices such as WAF, CDN, or load balancers. The certificate must be uploaded and synced to these network devices, otherwise it will not take effect.
If none of the above solutions resolve the issue, please contact technical support for assistance.
