Fire Stick Error CONN_ERR_3 — What It Means & How to Fix It

What Does This Error Mean?

Fire Stick error CONN_ERR_3 means a connection attempt timed out — the Fire Stick tried to reach a server and waited too long for a response. This is usually caused by a slow or unstable internet connection, a Wi-Fi signal that is too weak for streaming, or an overloaded server on Amazon's or the streaming service's end. Improving your network connection or waiting for server congestion to clear usually resolves it.

Affected Models

Fire TV Stick Lite
Fire TV Stick 4K
Fire TV Stick 4K Max
Fire TV Cube
Fire TV Stick (3rd Gen)

Common Causes

Your internet connection is too slow or has high latency, causing server requests to time out
The Wi-Fi signal at the Fire Stick location is weak due to distance from the router or physical obstructions
Amazon's Fire TV servers or the streaming service's servers are temporarily overloaded
Your router has been running for a long time without a restart and has high memory usage, slowing packet routing
A background app update or download on the Fire Stick is consuming available bandwidth

How to Fix It

Restart your router and your Fire Stick. Unplug the router from power for 60 seconds. Plug it back in and wait 2 minutes. Then restart the Fire Stick via Settings > My Fire TV > Restart. After both are back online, try your app again.

A router that has been running without a restart accumulates memory errors that cause slow packet forwarding. Regular router restarts (every 1 to 2 weeks) prevent this type of timeout error.
Check the Fire Stick's Wi-Fi signal strength. Go to Settings > Network. Look at the signal strength indicator. If it shows anything below 'Good,' the Wi-Fi signal is too weak for reliable streaming. Move the Fire Stick closer to the router or use the included HDMI extender cable to reposition it.

The HDMI extender cable (included in the box) moves the Fire Stick a few inches away from the TV. This alone often improves signal strength significantly, since the TV body can block Wi-Fi signals.
Switch to the 5 GHz Wi-Fi band if your router supports it. Go to Settings > Network > select your Wi-Fi network. If your router has separate 2.4 GHz and 5 GHz networks, try the 5 GHz one. It is faster and less congested if you are within 20 to 30 feet of the router.

In homes with many neighboring Wi-Fi networks, the 2.4 GHz band becomes congested and slow. The 5 GHz band has more available channels and less interference, resulting in more consistent speeds.
Pause any background downloads or app updates. Go to Settings > Applications > Appstore. Turn off 'Automatic Updates' temporarily. Also check if a large app update is currently downloading by going to Settings > My Fire TV > About > Storage — active downloads consume bandwidth.

The Fire Stick downloads app updates in the background. If a large update is running simultaneously with streaming, it can consume enough bandwidth to cause connection timeouts.
Check Amazon's service health status. Visit downdetector.com and search for 'Amazon Prime Video' or 'Amazon Fire TV.' If there is a current service disruption, CONN_ERR_3 may appear on all Fire Sticks — it is not specific to your device.

Amazon service outages, while rare, do happen. If many users are reporting connection issues simultaneously, waiting is the only fix.

When to Call a Professional

If CONN_ERR_3 occurs on every app and every network you connect the Fire Stick to, the networking hardware on the device may be failing. Contact Amazon customer service for warranty support.

Frequently Asked Questions

What internet speed do I need for the Fire Stick to work without errors?

Amazon recommends these minimum speeds: 1.5 Mbps for SD streaming, 5 Mbps for HD, and 15 to 25 Mbps for 4K HDR streaming. These are speeds measured at the Fire Stick — not at your modem. Wi-Fi signal loss between the router and Fire Stick can significantly reduce effective speeds. For a household with multiple streaming devices, a 100 Mbps or faster plan is recommended. You can test the Fire Stick's actual speed at Settings > Network > Check Network.

CONN_ERR_3 only happens in the evenings. Why?

Evening hours (7 PM to 11 PM) are peak internet usage times. Your ISP's network and streaming services' servers are under maximum load during these hours. This can slow connections and cause timeout errors that do not occur during off-peak hours. If your ISP regularly throttles traffic during peak hours, a speed test at 3 PM versus 9 PM will show a significant difference. Consider upgrading to a higher speed tier from your ISP if this is a recurring issue.

I have fast internet but still get CONN_ERR_3. What else could it be?

Fast internet speed does not guarantee low latency (ping time). High latency — even on a fast connection — can cause connection timeout errors. Run a speed test that also shows ping (try speedtest.net) and look for ping times above 50 ms to streaming servers. Also check if your router uses a technology called NAT overload or PAT — on cheaper routers, this can create connection tracking tables that become congested and cause random timeouts.
