> Narciso always needs the network and has no offline mode: what happens when the connection drops and which addresses not to block on the shop's network.

Last updated: 22 October 2026. Source: https://narciso.io/en/docs/connessione-a-internet/

Narciso **always works connected to the server**: the data is on the server and not on the salon's computer. There is no way to use it without a network. When the connection drops, the program stops, shows a warning and retries by itself.

## Type of connection

The program does not state a minimum speed. You need a line that can load images, videos and attachments without dropping: an unstable line is noticed immediately in the chat and in social publishing. There is no program limit on working on several workstations at once; the limit is that of the shop's line.

## When the connection drops

If the server does not respond, or the browser reports that it has no network, the dark window **«Connessione momentaneamente interrotta»** (Connection temporarily interrupted) appears full screen, with the text «Il gestionale sta tentando di ristabilire il collegamento con il server in modo automatico. I dati inseriti nel modulo non sono andati persi.» (The management program is trying to re-establish the connection to the server automatically. The data entered in the form has not been lost.).

Under the text a status line switches between three messages:

- «Riconnessione automatica attiva» (Automatic reconnection active);
- «Verifica connessione in corso...» (Checking connection...) while the program tries to reconnect;
- «Server non ancora raggiungibile, nuovo tentativo tra poco...» (Server not yet reachable, trying again shortly...) after a failed attempt.

| Button | What it does |
|---|---|
| **Riprova ora** (Try again now) | Tries to reconnect straight away. It stays grey while it is trying |
| **Ricarica pagina** (Reload page) | Reloads the whole page, like pressing F5. Use it if the screen does not disappear after about a minute |

The program retries by itself at short intervals. When the connection comes back the screen disappears and you carry on from where you were, with the data re-read from the server. If the screen stays for more than a few minutes, check the salon's connection, for example by opening another website. If the internet works but Narciso does not, contact support (see [Support](https://narciso.io/en/docs/assistenza/)).

### There is no offline mode

The program does not queue what is done without a network and does not keep local copies of appointments or sales.

> **Warning.** What you were typing in a window stays on screen until the page is reloaded. With **Ricarica pagina**, or by closing the browser, whatever had not been saved is lost.
>
> An action started just as the network dropped may fail with an error message. When the network comes back, always check whether the appointment, sale or message was recorded before doing it again: otherwise you risk a duplicate.

## Program update

During a program update the pages may fail to load for a moment. Narciso stays on the «Caricamento…» (Loading…) screen and retries by itself; as soon as the server is available again the page reloads. You do not need to do anything.

## Access check not available

A small yellow notification may appear at the top with the text «Verifica dell'accesso momentaneamente non disponibile: riprovo in automatico…» (Access check temporarily unavailable: retrying automatically…). It appears when, because of a temporary fault, the server cannot check whether the session is valid. **You are not logged out**: the program repeats the request by itself. If the check still fails after several attempts, the operation in progress shows an error and must be repeated after a short while.

## Chat and real-time updates

The chats, the message lists, the barcode readers and some alerts arrive through a continuous connection to the server (WebSocket). If a company network, a proxy or a filter blocks this type of connection, the chats do not update by themselves and new messages appear only when you reload the list. After a network drop the connection is re-established by itself, but messages that arrived in the meantime may appear only at the next update.

## Addresses not to block on the shop's network

If the shop's network has a filter (firewall, filtering DNS, parental controls) it is best to allow these services, otherwise some functions will be missing.

| Service | What it is for | If it is blocked |
|---|---|---|
| `app.narciso.io` and Narciso's subdomains, including the one for chat media | The program itself, the chat images and attachments | The program does not open or attachments cannot be seen |
| Cloudflare | Anti-robot check on the login page | You cannot log in |
| `unpkg.com` | PDF file preview | PDFs do not open in preview |
| OpenStreetMap (`nominatim.openstreetmap.org`) and ArcGIS (`server.arcgisonline.com`) | Finding the coordinates of an address and showing the map of the locations | Addresses not found, empty location map |
| `dns.google` and `disposable.debounce.io` | Checking the email address when you connect a mailbox or a PEC | The address check does not start |
| `youtube.com` | Video preview in the Social section | Previews not visible |
| Services of the platforms you connect (Meta, TikTok, Pinterest, Google, Stripe, SumUp) | Authorisation windows for the connections | The connection is not completed |
