To resolve this issue, ensure to import the issuer root and intermediate CA of the certificate installed on the backend server. Pulse Secure will pre-install all public certificate authorities at the time of the release. However, this may be a problem if the Pulse Connect Secure device is running an older version (older than 5 years) or if the backend server is using a certificate issued from a private CA. Please follow the instructions below to install the certificate chain on the Pulse Connect Secure device.
- Login to the admin console
- Navigate to System > Configuration > Trusted Server CAs
- Click Imported Trusted Server CA button
- Next to Import From, click Browse
- Select the certificate file to import
- Click Import Certificate
Note: If the backend server is using a self-signed certificate, then install a copy of the self-signed certificate under Trusted Server CAs. Administrator will need to make a note that if the self-signed certificate is changed, the new certificate must be installed on the device to avoid the following message.
