# Sync not working

Please try the following steps to resolve sync issues:

#### 1. Update the app

* Make sure you’re using the latest version of UpNote on all your devices.
* Go to the App Store or Settings > Help > Check for updates to update the app.

#### 2. Confirm your account

* Ensure you’re **signed in with the same account** on all devices to sync your notes.
* You can check this in Settings > My Account.

#### 3. Check your internet connection

Sync issues are often related to unstable connections. Try these steps:

* Toggle your Wi-Fi off and on 
* Restart your router
* Restart the UpNote app
* Restart your device
* Try connecting to a different Wi-Fi network

#### 4. Check your connection to UpNote servers

Your device may be unable to sync if the the connection to UpNote servers is blocked.

To test this:

* Open:
  * Terminal (Mac / Linux), or
  * PowerShell (Windows)
* Paste the commands below (they only check the connection to our servers and will not affect your device):

```
ping firestore.googleapis.com
ping www.googleapis.com
ping identitytoolkit.googleapis.com
ping securetoken.googleapis.com
ping us-central1-get-senna.cloudfunctions.net
ping firebasestorage.googleapis.com
ping api.getupnote.com
ping download.getupnote.com
```

If you do not receive any replies, it likely means the connection is being blocked. Some users have reported that enabling global mode in their VPN resolved the issue.

#### 5. Check VPN, antivirus, or firewall

* Toggle any VPN on your device
* Make sure your antivirus or firewall isn’t blocking UpNote’s connection

#### 6. Company network restrictions

* If you’re on a company network, the connection to UpNote’s servers may be blocked.
* Please [let us know](/resources/contact-us.md) if your administrator can adjust the firewall so we can provide a list of servers to allow

Please do not delete the app until all your data has fully synced to the server. Any data stored only on your device will be permanently removed and cannot be recovered if the app is deleted before syncing is complete.
{% endhint %}
