Connection troubleshooting checklist

Practical checks when a networking client cannot connect or update a subscription.

Practical checks when a networking client cannot connect or update a subscription.

How it works

First verify ordinary internet connectivity, then check that your subscription has not expired and that device or traffic limits are not exhausted.

Confirm that the client and link format are compatible. DNS problems, outdated settings, incorrect system time or a temporary service outage can cause failures.

What to keep in mind

When contacting support, include your client name, OS version and exact error message. Never send your password or a full secret-bearing subscription URL.
