1 FAQ and Troubleshooting

Access and Login

The page won't open in the browser.

First confirm the device is online and the address and port are correct, then check that the client is on the same subnet and the firewall allows the port. If it still fails after a device restart, contact the manufacturer or delivery party.

What if the administrator password is lost?

If another administrator account exists, log in and reset the password under "User Management". If all administrator passwords are lost, there is no default password or self-service recovery — contact the manufacturer or delivery party, keep the backup meanwhile, and do not delete business data.

The port is occupied or needs changing.

Administrators can change the service port under "System Settings" → "Network Settings"; restart the service or device after saving. If 6555 was occupied at first start, the system auto-selects within 3000–9000 — the actual port is in the handover notes or shown by the system. Update bookmarks and firewall rules together with the address.

Are phones and concurrent users supported?

Yes. Phones, tablets and computers all work with an adaptive interface. Multiple users can log in at once; "one person, one account" keeps records traceable.

Alerts and Mail

The test email fails to send.

Check in order: sender mailbox, password or auth code, SMTP server, port and the SSL switch. Most providers require an authorization code rather than the login password, and SMTP service must be enabled in the mailbox backend first. Try the auto-detected server and port, send a test again, and adjust manually against the provider's SMTP docs if it still fails.

Stock is below the threshold but no alert arrived.

Check in order: an enabled notification user exists; the warehouse default or material special alert is enabled; current stock is at or below the threshold; the reminder time has arrived and matches device time; no alert was already sent today for that material; the mail configuration works. Checks run every minute, at most one reminder per material per day.

Materials and Warehouses

Why did operation records disappear after deleting a material?

Deleting a material also deletes its historical operation records — unrecoverable. For materials with journal history, prefer "disable" over "delete" to keep records and statistics intact.

Why can't the warehouse be deleted?

Deletion is refused while materials remain. Move or delete them first, then delete the warehouse — confirming first whether their history still matters.

Backup and Upgrades

Data unchanged after restoring a backup.

Restoring replaces the data but loads only after restarting the service or device as prompted. Log in again after the restart. If still unchanged, verify the right backup file was chosen and the restore completed.

How do I upgrade?

Upgrades come from the manufacturer or delivery party. Create and download a backup first, follow the handover instructions, then verify warehouses, materials, stock, accounts and alerts afterwards. Never replace program files yourself.

How to migrate data when replacing the device?

Have the manufacturer pre-install on the new device, then restore business data from a backup. Log in with an account that exists in the backup and verify warehouses, materials, stock and operation records.

Is data in the cloud?

No. Business data stays on the device with no public-cloud dependency; the actual reach is decided by the enterprise network and firewall policy.

If a problem cannot be solved on your own, contact the manufacturer or delivery party with the product version, access address, symptoms, steps taken, time of occurrence and screenshots for fast triage.
