Tips and troubleshooting

Use these official guides to narrow down common connection, account, DNS, platform, and route issues. If the issue continues, contact support with the device, route, and error details.

• Connected but no internet

  Check DNS, route state, sign-in, local network, and conflicting proxy tools.

• Connection failed

  Check local network, sign-in state, system permission prompts, route availability, and device time.

• Slow connection

  Compare routes, local network quality, background traffic, and target service behavior.

• Android connection permission

  Check the Android network connection permission prompt, sign-in state, app restart, and route choice.

• Windows connection service check

  Check sign-in, local network, system time, proxy conflicts, security software, and route choice.

• Private DNS conflict

  Check Android Private DNS, browser secure DNS, other proxy tools, and local network settings.

• Some websites or apps not working

  Isolate whether the issue is caused by service region rules, account status, DNS, route choice, or local network.

• Account sign-in and device status

  Check sign-in failures, expired sessions, verification codes, device time, network state, and beta client version.

Connection quality can be affected by local networks, route status, and target services. CityLink Global does not promise fixed speed or availability for every app or website.
