Hi Piotr,

Allowing communication with the following should be enough to have DIS running:

• https://login.microsoftonline.com/*
• https://aadcdn.msftauth.net/*
• https://*.dataminer.services/*
• https://api.skyline.be/*

On top of that, if you want to connect your DIS to some DataMiner Agents, you'll simply have to allow communication with those agents.

For debugging on a DataMiner Agent, the necessary info will be provided when starting up the Remote Debugging Monitor tool (msvsmon.exe).
More info on that in the DIS help sections:
- DIS reference/DIS settings/DMA
- Debugging QActions and Automation scripts/Preparing to debug on a remote DataMiner Agent
