Problem: When turning on a secondary cloud connector (for redundancy purposes) it replaces the existing connector from the tenant portal. Only one connector will be visible, and when investigating each connector control panel on the host servers, one will appear to be running while the other is stopped or when started will hang indefinitely.
Resolution: This is often the case when a machine carrying the connector installation is cloned, as is often seen when using virtual machines. The cloud connector software is unique in that it must be installed separately for every instance. Only when the connector tool is installed independently will the tenant display multiple connectors.
