Gas Turbine mark VI server Cimplicity software problem

i am using mark VI in my gas turbine. The hmi 'GT4SVR' not showing parameters in the cinplicity '.cim' screens. However, all other softwares are working and i can see logics online at toolbox software. But when i opened GT4SVR.gef project workbench file, it shows that ' the server is not online in GT4SVR'.

need a solution, i have given previous backup image, but same problem. Communication is ok, because toolbox ia working

It looks like a cimplicity problem, but further investigation is needed to pinpoint the issue. I would look at the Status.log file to see if Cimplicity is spitting out any more errors.
