Here is the anonymized and summarized report:
Summary of Issue¶
A user reports persistent problems when attempting to start sessions on Maxwell display nodes, specifically:
- FS display nodes (max-fs-display.desy.de:3389)
- ITT display nodes (max-itt-display.desy.de:3389)
The issue manifests as a frozen or incomplete session initialization screen (e.g., an SSH authentication prompt with no further progress). The user notes that this problem previously occurred on the ITT nodes in August and was resolved, but now affects both FS and ITT nodes simultaneously.
Possible Solutions/Next Steps¶
- Check Browser/Client Compatibility
- Ensure the browser (or FastX client) is updated and supports the required protocols (e.g., WebSockets for FastX4).
-
Try an alternative browser (e.g., Firefox, Chrome) or the FastX4 client for better reliability.
-
Session Persistence
- If using a browser, verify that the session is not being blocked by extensions (e.g., ad-blockers) or network policies.
-
For SSH-based access, ensure the connection is stable and not interrupted by firewalls/VPNs.
-
Node-Specific Load
-
The FS nodes (
max-fs-display) are shared and may experience high load. Try:- Using
max-display.desy.de:3389(general access) if dedicated nodes are unavailable. - Submitting a batch job for resource-intensive tasks instead of interactive sessions.

Contact Support
- If the issue persists, escalate to the Maxwell support team with:
