 Issue description       

When users attempt to access the ADAudit Plus web console in a browser, they may encounter a warning message stating that the “Connection is not secure” or the “Site is not secure.”
This message indicates that the browser does not trust the SSL/TLS certificate used by ADAudit Plus.

Such warnings can discourage end users from logging in, impact administrator trust, and disrupt key operations such as auditing configuration or accessing reports securely over HTTPS.

 Prerequisites   

Before resolving this issue, ensure the following requirements are met:

• You have administrator access to the ADAudit Plus server and the web console.

• You have a valid SSL certificate (either self-signed or issued by a trusted Certificate Authority (CA)).

• The SSL certificate must be created for the exact hostname used to access ADAudit Plus (e.g., adauditplus.yourdomain.com).

• The ADAudit Plus service is running and accessible.

 Possible causes   

The “Site is not secure” warning generally occurs due to SSL misconfigurations or certificate issues. Below are common causes:

• Expired SSL Certificate: The installed SSL/TLS certificate has passed its expiration date, making it invalid for secure communication.

• Invalid SSL Certificate: The certificate currently bound to the ADAudit Plus web service does not match the domain name or hostname being used to access the console.

• Self-Signed Certificate: ADAudit Plus uses a default self-signed SSL certificate that is not inherently trusted by browsers. Users may see warnings until a trusted CA-signed certificate is applied.

• Incomplete Certificate Chain
  Intermediate or root CA certificates are missing, preventing browsers from validating the trust path of the SSL certificate.

• Improper Reverse Proxy Configuration
  If ADAudit Plus is hosted behind a reverse proxy, the proxy server may not have a valid SSL certificate applied even though ADAudit Plus itself is configured correctly.

 Resolution   

Follow the steps below depending on your deployment configuration.

 Step1: If accessing ADAudit Plus directly 

• Bind a valid and trusted SSL certificate issued by a trusted CA in ADAudit Plus.

• Ensure the certificate’s Common Name (CN) or Subject Alternative Name (SAN) matches the URL used to access ADAudit Plus (e.g., adap.yourcompany.com).

• Restart ADAudit Plus after certificate installation to apply changes.  

 Step 2: If a reverse proxy is used 

• Configure your reverse proxy server to use a valid SSL certificate. This process varies depending on the proxy software you use.

• Ensure the proxy is configured to serve HTTPS connections externally.

• The internal connection between the reverse proxy and ADAudit Plus can remain on HTTP, while users access the application securely via HTTPS.
