Basically, the client was prompting me with a message with SSL error with code 61. I looked it up on Google and found this script that solves the problem.
# Version: 0.1
# Author: Peter Dyson <email@example.com>
# Purpose: A workaround until Citrix gets their act together and packages up a better install script.
# What it does: downloads and installs Thawte root certs in the required location.
# change the install dir to be whatever you need, you may have used a local dir in your homedir,etc.
echo Current directory is: $STARTDIR
echo Creating temp download dir in $STARTDIR...
echo Fetching Thawte Root Certs...
echo Unzipping Thawte Root Certs...
echo Copying Thawte Root Certs to $CERTINSTALLDIR and renaming them...
echo This step uses sudo, enter your user password to run this step as root:
sudo cp "Thawte Server Roots"/ThawtePremiumServerCA.cer $CERTINSTALLDIR/ThawtePremiumServerCA.crt
echo Removing temp download dir...
rm -rf cert_download
echo Citrix SSL Cert fix complete!
