How to fix IBM Spectrum Accelerate's Communication Loss error after successful deployment?
Deployment of Spectrum Accelerate was successful. All modules are running; 
XIV GUI goes to a "Connection Rejected" state; 
Then, after 2 seconds, it quickly and permanently goes to the "Communication Loss" state; 
Even after clean re-deployments (with reboot of servers after VM deletion), the issue persists. Pl. let me know if you know why this occurs. I have also checked the Certificate and added it again on the GUI.
Did you ping the management IP address from you monitor PC ? Is there firewall between Spectrum Accelerate and your monitor PC ? Did you use the right username and password ?
Did the deployment diagnostics stage pass successfully? If not, what were the errors/warnings?
did you find an answer for this urajan01, I'm seeing a similar issue
