The office address changed, or its sharing port is in use

Steps

1. Open Office & devices on the host and select Check connection.
2. If sharing works but its address changed, leave both apps open on the normal office network, refresh nearby, then use Sync now on the laptop.
3. For a new laptop, use the currently discovered office or create a fresh connection code with the host’s current reachable address.
4. If sharing cannot start because a port is in use, close another copy of the app and retry. If necessary, an administrator can select a free port under Retry office sharing → Advanced connection settings.
5. After changing a port, run Set up office network again. Existing devices must rediscover the same host; if discovery is blocked, ask your administrator to review the saved endpoint rather than reset business data.

Check that it worked

The host check passes and an approved laptop reaches the same company with the current address and port.

Still stuck?

For an office spanning VLANs or a routed VPN, ask the network administrator for a reachable host address and narrowly scoped rules. Automatic local discovery may not cross those boundaries.
