The line in the log says it is not able to get the viewuser password from the mcsdk10 call.
This means that the viewuser password is corrupted or lost in memory in MCS.

Resolution

Run the change-passwords script to update viewuser, it can be the same password that is already being used or a new password.

The script restarts MCS to update all configuration files and MCS with the viewuser password.
