| DNS | Matches the route |
Run a connection test twice. Repeat to confirm stability.

❌ Warning signs:
- No pages load
- Login prompts repeat
- The original IP remains
- The route disconnects
Write down the error. Retest after each change.
| Issue | Cause | Fix |
|---|---|---|
| No connection | Wrong host or port | Copy values again |
| Login loop | Old credentials | Refresh the login |
| Same IP | Inactive route | Reopen controls |
| Slow pages | Distant endpoint | Choose a closer region |
| DNS mismatch | Local resolver | Review DNS options |
How proxies work in browsers
A browser sends selected requests through an intermediary endpoint, which contacts the destination and returns the response. The Firefox proxy settings model offers browser-level control, while Chrome follows system controls.
| Feature | Benefit |
|---|---|
| Browser routing | Other apps stay unchanged |
| Protocol choice | Better compatibility |
| US locations | Local QA |
| Stable credentials | Fewer errors |
| Dashboard access | Easier management |
