ERROR: SAP B1 HANA - Failed to connect System Landscape Directory

I am using SAP Cloud Aplication Library to test SAP Business One 9.3, version for SAP HANA PL4.

I must have closed the SAP B1 Client without fully logging out, and after I did this I suspended the instance in SAP CAL.

Now I keep getting the "Failed to connect to SLD" even after rebooting the instance and restarting the VM.
