Update Clientless RDP Certificate
When your certificate is expired, you need to replace it on the Clientless RDP Gateway. Please make sure to rename the new certificate name to clientlessrdpcert.pfx.
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
