DNS Issues with Nooks

Last updated: December 17, 2025

Intro - what is DNS and how to fix it for Nooks?

At a very basic level, DNS (Domain Name System) is like the address book of the internet. Every website lives at a specific numerical address (called an IP address), like 142.250.190.78 for Google. But remembering numbers is hard, so we use easy names like google.com.

  • DNS translates the website name into its actual address so your computer can find it.

  • To fix: we recommend Google's official instructions to configure your DNS settings to use Google's DNS:

How DNS Filtering Affects Nooks

Certain DNS settings can interfere with the proper functioning of Nooks (particularly in relation to Google Firebase Realtime Database.)

  • One common culprit is Quad9 (9.9.9.9), which employs aggressive filtering that may block necessary requests to Firebase and other Google services that Nooks uses. As a result, key features of Nooks can break or experience degraded performance.

Symptoms of DNS filtering


1. Salesfloor Functionality Breaks
Nooks relies heavily on Google Firebase Realtime Database for real-time interactions and state management. When DNS filtering blocks Firebase requests, most of the salesfloor features will fail, preventing users from:

  • Seeing user video or avatars in the salesfloor,

  • Joining and leaving groups,

  • Seeing live calls.

Audio may continue to work but quality will be degraded.

2. Call Transcriptions Fail
Realtime call transcriptions services also depend on Google Firebase Realtime Database, and won't appear if this is blocked by your DNS

3. General Performance Degradation
Even if some functionality remains operational, DNS filtering can still cause:

  • Increased latency while dialing

  • Unreliable prospect connection notifications

  • Degraded audio quality.

Recommended DNS Configuration

DNS settings are fairly simple to change for your wifi network.


To avoid these issues, we strongly recommend switching your network to use Google's Public DNS (8.8.8.8 and 8.8.4.4), which ensures full compatibility with Nooks.

How to update DNS settings

Follow Google's official instructions to configure your DNS settings:

For most users, updating DNS settings can be done at the router level or within individual device network settings.

Conclusion


If you're experiencing issues with Nooks, particularly with salesfloor functionality, call transcriptions, or general app performance, your DNS settings may be the culprit. Switching to Google Public DNS can resolve these problems and ensure that all Nooks features
