Step-by-Step Resolution

Expand each section as needed

1
Symptoms
Info
Recommended validation or troubleshooting step
- SaaS applications reject login while VPN is active but work off VPN. - Users see unusual location/risk alerts during authentication. - Specific apps fail while others continue to work.
2
Likely Causes
Info
Recommended validation or troubleshooting step
- SaaS risk engines flag shared VPN egress IP ranges. - Geolocation-based policy blocks current VPN exit region. - Conditional access/trust policy mismatch between SaaS and VPN routing.
3
Confirm scope, user impact, and reproduction
Info
Recommended validation or troubleshooting step
Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.
4
Validate prerequisites and application/session state
Info
Recommended validation or troubleshooting step
Confirm the user is signed in with the correct corporate account, system time is accurate, network/VPN connectivity is stable, and the application is not running in offline or limited mode.
5
Run safe diagnostics from the Commands section
Info
Recommended validation or troubleshooting step
Use the command snippets below to collect non-destructive diagnostics. Capture output in the ticket when escalation may be required. Avoid deleting profiles, cached credentials, or managed app data unless the runbook or admin approval explicitly allows it.
6
Apply safe remediation steps
Info
Recommended validation or troubleshooting step
- Capture blocked app, error text, timestamp, and apparent sign-in location. - Compare behavior on approved alternate egress profile if available. - Coordinate with SaaS admin to validate trusted IP/location configuration. - Avoid routing around corporate policy via unauthorized personal tunnels.
7
Escalate when access, policy, or security controls are involved
Warning
Review carefully before proceeding
- Multiple users are blocked in the same region/egress profile. - SaaS trust policy needs updates for approved enterprise egress ranges. - Security review is required due to high-risk sign-in detections.
Admin review or admin rights may be required for this step.
