Environment

Web Applications

Cause 1

There is a problem with the certificate and it will need to be modified and re-issued.

Resolution 1

1. Open the PME web browser using Chrome.

2. Right-click anywhere on the login page > Inspect

3. Select the three dots menu > More tools > Security

Security menu in developer tools

4. Refer to the Security overview to identify issues with the certificate. In the example screenshot below, the cause of the issue is due to the certificate not having at least one Subject Alternative Name:

Subject Alternative Name missing

Cause 2

The URL entered is incorrect or the HTTPS configuration is incomplete.

Resolution 2

Ensure the URL entered into the web browser matches either the "Issued To" field of the certificate or one of the "Subject Alternative Names". Refer to the "Configure PME for server certificates" section of the PME System Guide to ensure it was configured correctly.
