DNS: Separate Name Resolution from Connectivity
DNS resolves domain names to IP addresses. Check DNS-related options in Settings and whether the current Config includes DNS settings; the configuration file may affect actual behavior. If you have no specific requirement, keep the working settings as they are. If you have a prescribed DNS setup, enter the values from your source and record the original settings first.
If a domain won’t open but its IP address responds, DNS may be involved, but that alone is not conclusive; HTTPS sites also depend on certificates and hostnames. After changing DNS, make a new request rather than relying on a cached result. Changing DNS does not fix server parameters. Avoid changing IPv6, rules and server settings at the same time, or it will be harder to identify the cause.
Test Method: Keep the Measurement Consistent
Test Method determines how relevant tests are performed. Review the available options in Settings and choose one. Methods may test different stages of a connection, so compare results only when the method and network conditions are similar. After changing methods, don’t treat the old and new results as a direct measure of server quality.
After choosing a method, return to Home and run Connectivity Test, then try the service you actually need. A successful test does not mean every website is accessible, and a failed test needs to be considered alongside its target and your current network. If only one test method fails, first check its requirements instead of deleting every server.
Today Widget: Verify the Status After Using Shortcuts
Today Widget provides quick status checks and actions where supported by the system. Check the related options in Settings, then add the widget using the method available in your current system. If your system or app version does not show the widget, don’t change connection settings just to look for it.
After using the widget, return to Home and check the server, connection toggle and Global Routing. Widget status may take time to refresh and does not replace a connection test. If information is visible on the Lock Screen, review system display permissions to avoid exposing unnecessary server notes in public.
iCloud Sync: Not the Same as a Subscription Update
iCloud sync transfers data supported by the current version between your personal devices. It is separate from refreshing a server list with an existing provider. Check the sync option in Settings, confirm the devices use the intended iCloud account, make sure system access is allowed and verify that the network is available. Save important configurations before enabling sync, then compare local and cloud contents so you don’t mistake older data for new settings.
After changing something on one device, allow time for sync and check the result on the other device instead of assuming connection status, system permissions and every setting will transfer completely. Server passwords, subscription URLs and keys are sensitive; understand what data is synced. System VPN permissions must still be confirmed separately on each device.
Diagnostics: Capture the Conditions for One Issue
Diagnostics lets you collect and review connection-related information from its entry in Settings. First note the network, selected server, Global Routing mode and steps to reproduce the issue, then run the available diagnostic tools. Try to reproduce one specific issue rather than generating unrelated requests that obscure useful information.
Review the output to identify where the problem occurs: connection failure, authentication failure, DNS resolution or an unexpected response from the destination. Diagnostics helps narrow down the cause; it is not a lasting conclusion about every destination. Before sharing logs, redact subscription parameters, authentication details, keys and unnecessary personal browsing records. Turn off detailed logging when you’re done if you no longer need it.
