Amazon Fire Stick Connection Error 4 — What It Means & How to Fix It

What Does This Error Mean?

Fire Stick Connection Error 4 means the device connected to your Wi-Fi network but cannot reach Amazon's servers on the internet. Your Fire Stick can see your router, but the internet traffic is not getting through. This is different from a Wi-Fi password error — the Wi-Fi join succeeded, but something beyond your router is broken. Common causes include a router DNS problem, an ISP outage, or a router setting that is blocking Amazon's server addresses.

Affected Models

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

Common Causes

Your router is connected to the internet but your ISP is experiencing a partial outage affecting Amazon's services
The DNS settings on your router are misconfigured or using a DNS server that is currently down
A parental control or content filtering setting on your router is blocking Amazon's server addresses
Your router's firewall has blocked the ports or IP ranges that Fire TV uses to communicate with Amazon
The Fire Stick received incorrect network settings (IP address or gateway) from your router's DHCP service

How to Fix It

Restart your router and modem. Unplug both from power. Wait 30 seconds. Plug the modem in first and wait 2 minutes for it to reconnect. Then plug the router in and wait another 2 minutes. Finally, restart your Fire Stick from Settings > My Fire TV > Restart.

A full network stack restart clears stale routing tables and forces the router to re-establish a fresh connection from your ISP. This fixes the majority of Connection Error 4 cases.
Check if other devices on the same network can reach the internet. Open a browser on your phone or laptop (connected to the same Wi-Fi) and try loading amazon.com specifically. If amazon.com loads fine on another device, the issue may be specific to your Fire Stick. If amazon.com also fails on another device, your ISP connection or DNS is the problem.

Test amazon.com specifically — not just any website. Connection Error 4 is about reaching Amazon's servers, so confirming amazon.com is reachable from other devices narrows down the cause.
Change the DNS settings on your Fire Stick to use Google's DNS servers. Go to Settings > Network > select your Wi-Fi network > Advanced. Set the DNS 1 to 8.8.8.8 and DNS 2 to 8.8.4.4. Save and reconnect.

Your router's default DNS may be provided by your ISP and can sometimes fail or become slow. Google's DNS servers (8.8.8.8) are reliable and free.
Check your router's parental controls and firewall settings. Log into your router's admin panel (usually by typing 192.168.1.1 in a browser). Look for content filtering, website blocking, or firewall rules. Make sure Amazon's services are not blocked. Look for any custom rules that might restrict certain IP addresses or ports.

If you use a third-party DNS filter service like Circle or OpenDNS, it may be filtering Amazon traffic. Try pausing or disabling it temporarily to test.
Forget the Wi-Fi network on your Fire Stick and reconnect from scratch. Go to Settings > Network > select your network > Forget This Network. Then go back and reconnect by selecting the network and entering your Wi-Fi password again. This forces the Fire Stick to request fresh network settings from your router.

Occasionally the DHCP settings the router gave the Fire Stick become stale or conflicting. Forgetting and rejoining the network gets a fresh set.

When to Call a Professional

Connection Error 4 is almost always a network configuration issue you can fix yourself. If none of the steps below work, contact your internet service provider — they can check your modem and connection from their end. You can also contact Amazon support at 1-888-280-4331 if the issue appears specific to Amazon's servers.

Frequently Asked Questions

Why can my phone use the internet but my Fire Stick cannot?

Your phone and Fire Stick may be getting different network settings from your router. For example, a parental control filter applied only to certain devices, or a guest Wi-Fi with different routing rules, can affect one device but not another. Also, phones often use mobile data automatically when Wi-Fi has issues — so the phone appears to work fine while actually switching away from your home network.

What ports does Fire TV use that might be blocked?

Fire TV primarily uses port 443 (HTTPS) for secure communication with Amazon's servers. It also uses port 80 (HTTP) for some connections and specific ports for streaming. If your router's firewall is set to 'high' security, it may be blocking outbound connections on non-standard ports. In most home routers, lowering the security setting from 'high' to 'medium' resolves this.

Could my ISP be blocking Amazon?

It is technically possible but very rare. Some ISPs throttle streaming traffic rather than blocking it outright. If you notice slow streaming speeds or buffering in addition to Connection Error 4, throttling may be a factor. A VPN can sometimes help verify this — if streaming works through a VPN but not without one, throttling or routing issues with your ISP are likely.
