To debug your setup or environment and network just use the testlink python example in pycharm, if that works, it's definitely a robot issue. I had no trouble at all with the testlink python examples - what version of testlink and what version of robot? without that info, cannot really help.
Hi, could you please provide more details about the issue? What are the expected and actual results?
If the issue is related to the Robot Framework plugin (https://plugins.jetbrains.com/plugin/7415-robot-framework-support), please report it to the plugin's developer.
