1
Symptoms
Info
Recommended validation or troubleshooting step
- VPN shows connected but the user cannot browse or reach internal sites. - Only internal resources fail, or only public internet fails while VPN is active. - Issue started after network change, VPN update, or device wake/resume.
2
Likely Causes
Info
Recommended validation or troubleshooting step
- DNS resolution or route push issue. - Split-tunnel expectations misunderstood. - VPN client/session state problem or local network conflict.
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
- Confirm what is failing (internet, internal resources, or both) and when it started. - Reconnect VPN cleanly and test on another approved network if available. - Collect route/DNS diagnostics and attach them to the ticket. - Avoid disabling security clients or using personal remote access tools as a workaround.
7
Escalate when access, policy, or security controls are involved
Warning
Review carefully before proceeding
- Routes, DNS servers, or tunnel policy appear incorrect. - Many users on the same VPN profile are affected. - Security/network teams must review tunnel and access policy configuration.
Admin review or admin rights may be required for this step.
