After upgrading UIM to 20.3 with CABI bundled 4.30 there is a problem to access Operator Console with error message:

(!) Data Access Error - Dashboard failed to load


UIM 20.3

CABI bundled 4.30 and Wasp


- Wrong path for the certificate.pem in the cryptkey variable in the robot.cfg file on the cabi server.


Please follow up these instruction below that will lead you to resolve the issue with CABI dashboard:

Please review the UIM installer created certificate file (certificate.pem) in the security folder (C:\Program Files (x86)\Nimsoft\security\certificate.pem) as it is the symmetric key that is shared then used for communication with data_engine probe.

Copy certificate file to the remote UMP, UR, and CABI robots and provide the location of the file in the robot.cfg file by editing it in a text editor and adding into it as following (cryptkey = C:\Program Files (x86)\Nimsoft\security\certificate.pem.

Furthermore, if any impacted probe is not on the same computer where data_engine is present, copy the generated certificate file from UIM server (C:\Program Files (x86)\Nimsoft\security\certificate.pem) to the robot computer (where data_engine is not available) and update the robot.cfg file (C:\Program Files (x86)\Nimsoft\robot\robot.cfg) with the certificate (C:\Program Files (x86)\Nimsoft\security\certificate.pem) file location on that computer as mentioned above.
Note: No need to restart the robot.
