Ignition 8.0.15 redundancy with SSL

Hi All:

Thanks in advance for reading this post. I am trying to use ignition in redundant mode with SSL and with the self-signed certificate. while the gateway network and redundancy seems to work, after i add the gateway to vision client launcher, it logs the following error message in launcher.log " unable to parse redundant address ‘’". Then the configuration json file has the redundant address as empty for the application added to the launcher. Has any one had similar issue before?
