Cannot connect to platform after commissioning to FIPS mode

During the commissioning process, if a FIPS licensed is installed, a new default "tridium" certificate will be generated for TLS connections. If a certificate exemption was already approved for this host, a dialog should pop up indicating that the certificate for this host has changed, requiring the user to approve the new certificate before proceeding with the connection. In some cases, this dialog will fail to appear, and the connection cannot be made.

Two possible solutions are available.

  • Go to Workbench Tools > Certificate Manager, and go to the Allowed Hosts tab. Find an entry corresponding to the JACE you are connecting to (be sure to select the entry with the correct port), and delete it.
     NOTE: Do not worry about deleting entries from this store. The only consequence of deleting the wrong certificate in Workbench is that you may need to accept the exemption again the next time you connect.  
  • Close the platform connection in the Nav tree, reconnect using File > Open > Open Platform, and approve the certificate exemption when it pops up.
