A connection attempt to a SAS Viya workspace server from SAS Enterprise Guide fails with the following error if a firewall exists between them:

As a workaround, disable SSL for the object-spawner connection by completing these steps:

1. Stop the spawner:
      sudo systemctl stop  sas-viya-spawner-default
2. Create a backup copy of the /opt/sas/viya/config/etc/spawner/default/spawner.sh file.

3. Remove the following line in the spawner.sh script:
   if [[ ! -z "${sslPrivateKeyFile}" ]]; then
      spawner_options="${spawner_options} -sslpvtkeyloc ${sslPrivateKeyFile} -sslcertloc ${sslCertificateFile} -sslpvtkeypassfile ${sslPrivateKeyPasswordFile} -sslcalistloc ${sslCAListFile}"
   fi

4. Insert the following line where you removed the previous line:
   if [[ ! -z "${sslPrivateKeyFile}" ]]; then
      spawner_options="${spawner_options}"
   fi

5. Start the spawner:
      sudo systemctl start  sas-viya-spawner-default

Post Hot-Fix Installation Steps:

1. Add the sasServicePorts variable to the spawner definition located in the /opt/sas/viya/config/etc/spawner/default/spawner.sh file. This variable contains a comma-separated list of port values. Only one port is needed, but multiple ports are supported. The port values are used as listen ports for the launched servers. The ports need to be opened via the firewall:

2. Restart the object spawner:
   
   Red Hat Enterprise Linux 7.x (or an equivalent distribution) and SUSE Linux Enterprise Server 12.x:
      sudo systemctl restart sas-viya-spawner-default 
   
   Red Hat Enterprise Linux 6.x (or an equivalent distribution):
      sudo service sas-viya-spawner-default restart
