Symptoms
Dell can connect CLI using SSH over Secure Connect Gateway (SCG) but cannot connect to Unisphere connection over Secure Connect Gateway (SCG).
Unisphere can connect using IP address but is unable to connect using SCG.
Cause
This issue is caused by a missing network port or firewall connection over SCG.
Resolution
Check Firewall Settings.
Ensure that the firewall allows communication from the Secure Connect Gateway to the Unity on the required ports.
Confirm that network port 443 is open and allows SCG to communicate with the Unity array with Unisphere.
Once Port 443 is opened, the Unisphere connection using SCG should work.
