Common questions

Scanning works, but it will not connect

Make sure the service on your computer is running, that your phone and computer are on the same trusted local network or the same private network, and that the access token has not expired. The desktop version usually needs the plugin's LAN bridge enabled; restart DeepSeek Harness after changing the configuration.

The address opens, but the app says authentication failed

Get a fresh QR code from Settings on your computer, or type the access token again. Do not put the token in screenshots, logs or chat messages. A different strong token for each computer is recommended.

The connection drops after I leave home or the office

DSH Mobile reaches your computer over your local network or a private network you manage yourself. Check that your phone and computer are still on the same network. When you bring the app back to the foreground it fetches the state again and tries the candidate addresses.

I do not get approval or question alerts

First allow notifications for DSH Mobile in system settings, then check that the push bridge or in-app alerts are configured on your computer. Once you open the session, the approval card shows in the app; if another device has already answered, the card is settled.

A file will not open or export

Android uses the system file features to save or open files; iOS uses Files and the share sheet. Make sure the device has an app that can handle that file type, and check the app's file access permission.

How to report a problem

When you email us, please include: the app version, the plugin version on your computer, your phone's OS version, how you connect, the steps to reproduce, and any error message with sensitive parts removed. Please do not attach access tokens, QR codes, real session content, personal email addresses or secret files from your workspace.
