CloverDX Designer application starts as two processes: CloverDX Designer GUI and CloverDX Runtime. These processes need to communicate with each other over TCP protocol. You should allow the mutual communication with Allow access button.
Designer Stops Responding
Due to bug in Linux/GTK+, Designer runs out of number of open files as the backend opens the file
/etc/cups/client.cont many times.
As workaround, you can configure the printers in
/etc/cups/client.conf file, or add

Component Editor Not Working
In older Linux versions (e.g. Ubuntu 16.04 MATE or Linux Mint 18 Cinnamon), Eclipse platform may experience some problems related to the system’s GTK version. For example, when using GTK 2, the component editor in CloverDX Designer may not work properly.
In such a case, add the following parameter to
CloverDXDesigner.ini located in the root folder of your CloverDX Designer installation:
This parameter forces CloverDX Designer to run using GTK 2 which may fix the problem.
Note: do not use the parameter on systems using GTK 3 (e.g. Manjaro with KDE Plasma 5), as it may cause other problems (e.g. non-functional tooltips in the graph editor).
If you use CloverDX Designer with Subclipse plugin, and perform the following steps: In a project, create a directory
aaa, create a file
bbb, delete the directory
aaa, and rename file
aaa; you may encounter the message:
An exception has been caught while processing the refactoring 'Rename resource'. Reason: Problems encountered while moving resources. Error deleting markers for resource bbb. Resource aaa does not exist.
This problem is caused by caching resources by the Subclipse plugin and is not related to CloverDX.
If this message appears, refresh the project in Project Explorer.
CloverDX Designer by default accesses the following internet addresses:
Eclipse (188.8.131.52, 184.108.40.206) - automated check for Eclipse updates.
220.127.116.11 - anonymous CloverDX usage metrics
Designer is fully functional when used offline.
CloverDX Designer collects and reports usage information so we can learn from user experience. All communication is performed over HTTPS and we do not collect any personal or potentially sensitive data - no credentials, paths, component names, ..
System/Environment info (operating system version, screen resolution, memory parameters, java version, license number)
Statistics data (used component types, connection types, example projects - creating examples, example graphs - opening, welcome page interaction, tutorial progress - steps taken)
Important events (job execution - component count, job execution finished - result status - exception type in case of error, license events) Usage is collected only by CloverDX Designer. Nothing is sent from CloverDX server.
