Can't log into primary hub IM: Login Failed - Cannot locate specified domain


Article ID: 257907

DX Unified Infrastructure Management (Nimsoft / UIM)


When we try to connect to the primary hub with "Infrastructure Manager", the following pop-up appears: "Login Failed - Cannot locate specified domain".

The primary hub is not stable and seems to be restarting continuously. GUI's cannot be opened from IM and controller.log and hub.log don't clearly indicate any major issue.                      


Release : UIM 20.4


On the primary hub Nimsft/robot folder, the robot.cfg might be compromised/ missing sections.

This could be caused by System crash, system out of space, invasive AV or user error/file open in notepad saved by mistake. 


As the robot.cfg in the primary hub is compromised this must be restored. Either restore the robot.cfg from a backup or compare another working robot.cfg and recover the missing sections. 

Below is an example of a working robot.cfg from a primary hub:


   robotname = bserver
   hubip =
   robotip =
   first_probe_port = 48000
   set_qos_source = yes
   ip_version = ipv4 ipv6
   domain = mippa-bserver_domain
   hub = bserver_hub
   cryptkey = C:\Program Files (x86)\Nimsoft\security\certificate.pem
   reset_folder_acls = no
   copy_acls_from_programfiles = yes
   reuse_async_session = 1
 hubrobotname = bserver
   hubport = 48002
   access_0 = 0
   access_1 = 1
   access_2 = 2
   access_3 = 3
   access_4 = 4
   loglevel = 5
      TNS_ADMIN = 
      NIM_JRE_HOME = jre/jre8u282b08
      NIM_JRE_HOME_1_8 = jre/jre8u282b08
