This issue happens when the UVC user has no correct permissions on the Node.
Two cases are possible:
1. The Dollar Universe administrator has not granted the appropriate rights to the user.

2. There is a problem with the file u_fmsc60.dta that locally stores the security settings and is synchronized with UVMS.
When opening the file <DUAS>/data/u_fmsc60.dta, only a few lines are visible and the file does not look the same as for the rest of the nodes where the issue does not occur.
