HMTL 5 serial console does not work in SolusVM Client area - the blank page is shown, despite the fact that from the administrator area, it works as expected.
Option Disable Serial Console Access is checked in SolusVM > Nodes > localhost > Settings.
Login to SolusVM web interface.
Open SolusVM > Nodes > localhost > Settings.
Uncheck Disable Serial Console Access.
