Direct answer
Fast speed tests with slow browsing usually indicate DNS delay, overloaded target sites, wrong node selection, rule mismatch, packet loss or a test server that does not represent your real traffic.
What to check first
Treat connection symptoms as a layered support check: profile update, node availability, rule match, DNS result, local proxy port, system permission and target website behavior all need to be isolated.
- Test with one known-good node and one simple website first.
- Compare Rule mode and Global mode to separate routing from node availability.
- Check DNS logs, local proxy ports and system proxy settings.
- Record status messages and timestamps before contacting provider support.
Recommended handling
Keep the troubleshooting path narrow: confirm the profile, confirm the selected node, test Rule mode, read the log, then change only the setting that matches the observed status message.
Practical notes
- Change one setting at a time so the result is attributable.
- Use logs and timestamps when asking for provider or community support.
