How to allow Local Network Access for Nabla Echo

When using Nabla Echo during a video visit, your browser must allow Local Network Access so Nabla can connect to Echo on your computer and capture audio.

You’ll need to allow Local Network Access if:

• You’re using Nabla Echo

• The encounter is a video visit

• You haven’t allowed this permission yet (or previously blocked it)

If this access isn’t allowed, the encounter can’t start and audio won’t be captured.

Nabla Echo runs locally on your computer to securely access audio from your video visit.

Modern browsers like Google Chrome, Firefox, and Microsoft Edge require your approval before a website can communicate with local software. This is a standard security measure.

This is the simplest and most common case.

When starting a video encounter, your browser may show a pop-up saying it wants to connect to devices on your local network.

When the prompt appears, click Allow. You won’t be asked again.

Choose your browser below.

You can also change the permission manually.

1. Open Nabla in your browser

2. Look at the address bar

3. Click the padlock (🔒), microphone (🎙️), or tune icon

4. Go to Site settings

5. In Privacy and security, find Local network access

6. Change it to Allow

7. Refresh the page

Edge manages this permission slightly differently.

👉 Follow Microsoft’s official guide at this link.

Firefox uses its own Local Network permission model.

👉 Follow Mozilla’s official guide at this link.

• You won’t be prompted again

• You can click Start encounter

• Nabla Echo works normally during video visits

Try these quick checks:

• Refresh the Nabla page

• Make sure Nabla Echo is installed and running

• Fully close and reopen your browser
