VxRail "Mystic" not accessible

Hi,

Recently upgrade VxRail Cluster from 6.7 to 7.0.  Mystic was working fine after the upgrade. 

Just yesterday, we can't access "Mystic" via SSH and Web. Also, I can't access VxRail Manager via SSH but I can access it on the web.

Hope I can hear from you soon guys.

Thanks,

Jek
