Update Clientless RDP CertificateFollow
When your certificate is expired, you need to replace it on the Clientless RDP Gateway. Open a session to the Clientless RDP Gateway and run the following commands:
cd /etc/tomcat8 sudo rm -r clientlessrdpcert.pfx sudo wget urltocertificate -O clientlessrdpcert.pfx sudo nano server.xml
Search for the connector listening on 8443. Scroll to the right and update the password.
sudo service tomcat8 restart
