Overview

A cloud-hosted system may appear online while still being inaccessible to administrators or end users.

Symptoms

• Users report inconsistent or failed access to the affected service, device, or application.
• Normal business or home workflows are interrupted, delayed, or no longer reliable.
• The issue may be isolated to one user or may affect multiple systems depending on the root cause.

Cause

Incorrect firewall rules, NSG restrictions, service issues, credential errors, VPN requirements, or public IP problems can block access.

Resolution

Verify the VM is running, confirm network access rules, test remote access ports, review credentials, and check whether the issue began after a recent platform or security change.

1. Confirm the exact symptoms and identify who or what is affected.
2. Check for recent changes such as updates, password changes, hardware swaps, DNS changes, or policy adjustments.
3. Test the most likely root cause first and document all findings clearly.
4. Apply the corrective action in the least disruptive way possible and verify the issue is fully resolved.
5. Record the final outcome, any user communication, and any recommended follow-up work.

Prevention

Document cloud access paths clearly and review security groups before applying broad policy changes.

When to Contact Support

If the issue continues after standard troubleshooting, affects multiple users, involves data loss risk, or raises security concerns, it should be escalated to a qualified technician promptly.
