# What do the errors "Failed to Connect to CDN" and "Error syncing exchange instruments" while opening the Arrow mobile application mean?

> This error may occur if your internet connection is not stable or fluctuating.

## Short answer

This error may occur if your internet connection is not stable or fluctuating.

## How to resolve this issue

Check your internet speed and stability.

If there are no issues with your internet, try changing the DNS server to Google's or Cloudflare's public DNS on your phone. iRage uses Cloudflare as the Content Delivery Network (CDN). If your internet service provider's Domain Name System (DNS) server fails to support domains under Cloudflare, you may not be able to access iRage services like Arrow, Console, etc.

Try reinstalling the app. Use an alternate internet connection if the issue persists even after reinstalling.

Create a ticket if the issue persists even after following the above procedure.

Did you know? Arrow app works only on Android devices with version 6 and above and on iOS devices with version 11 and above. Clients using Android versions 5 and below or iOS versions 10 and below can access Arrow through any web browser by visiting Arrow.arrow.trade.
