Using a Proxy server Filr 3.0 Update Channel Registration fails with HTTP 500 Error

When the Filr, Filr Search or Filr MySQL appliance is in private network and the appliance is configured with a Proxy, the Online Update registration to either Micro Focus Customer Center or SMT fails from the Appliance Configuration Console (port 9443) > Online Update tile. The following error is displayed:

An error occurred while communicating with the server. Status code: 500 (The call failed on the server; see server log for details)

When looking through the /var/opt/novell/datamodel/logs/datamodel.stderr.out log file, the following error is logged:
suse_register  -E failed with a return code of 2

In order to complete the registration when the appliance is configured with a Proxy, the following steps must be followed:

1. SSH to the Filr Server using the Proxy Appliance
   a. SSH to the Proxy Appliance Public IP
   b. From Proxy appliance, SSH to the Filr Appliance 
   
   
2. If registering with the Micro Focus Customer Center, run the following command:
   suse_register -a email="<Email address>" -a regcode-filr="<14-digit Activation Key>" -d 2 -L  /var/opt/novell/va/logs/suse_register.log
   
   For example:
   suse_register -a email="john.doe@example.com" -a regcode-filr="12345678912345" -d 2 -L  /var/opt/novell/va/logs/suse_register.log
   
   
3. If registering to your local SMT server, run the following commands:
   a. /opt/novell/base_config/VAclientSetup4SMT.sh --yes --host <SMT-Server-Address>
   b. /usr/bin/suse_register -L /var/opt/novell/va/suse_register.log
   c. /usr/bin/zypper mr -ae 
   d. /usr/bin/zypper --gpg-auto-import-keys -x ref -s
   
   
4. Visit the Appliance Configuration Console (port 9443) > Online Update tile and hit refresh. It should now show the registered repository.
