DAZN Keeps Freezing? 10 Fixes for Lag and Buffering

DAZN freezes mid-fight, and you miss the knockout. The app locks up during a Premier League goal. I’ve dealt with this on three different devices over the past year, and the fix almost always comes down to your network, the app cache, or your device running out of resources.

#Why Does DAZN Keep Freezing?

Three things cause nearly every DAZN freeze: your internet connection, the DAZN app, and your streaming device.

On the network side, Wi-Fi dead zones, ISP throttling during peak hours, and too many devices sharing bandwidth all starve the stream. According to DAZN’s help center, the app needs a stable 10 Mbps connection at minimum. I tested on a 2024 Samsung TU7000 with 15 Mbps Wi-Fi and got constant buffering. Switching to Ethernet on the same connection fixed it instantly.

Cached data is another common culprit. The DAZN app stores temporary files that corrupt over weeks of heavy use, especially on Fire TV Stick and budget smart TVs with only 8 GB of storage.

Your device matters too. Smart TVs from 2019 or earlier often lack the RAM to run DAZN’s current app version without stuttering, and background apps eating up processing power make it worse. A TV with 1.5 GB of RAM that ran DAZN fine two years ago may struggle today because DAZN’s app has grown more resource-hungry with each update.

#How Do You Fix DAZN Network Issues?

Start with the fastest fixes first. Each step targets a specific root cause.

#Restart Your Router and Modem

Unplug your router and modem from power. Wait 60 seconds. Plug the modem back in first, wait for all lights to stabilize, then plug in the router. This clears IP conflicts and memory leaks that build up over days of continuous use.

I restart my Netgear Nighthawk every two weeks. Takes 90 seconds.

#Run a Speed Test

Open fast.com on the same device you stream DAZN on. DAZN needs 10 Mbps minimum for standard definition, 25 Mbps for 1080p, and 50 Mbps for 4K. If your speed falls below these numbers, the stream will freeze.

Compare your result to your ISP plan. Speeds below 50% of what you’re paying for point to a router, wiring, or ISP problem. According to Netflix’s speed recommendations, most streaming services share similar bandwidth thresholds, so a slow result here means other apps will struggle too.

#Switch to a Wired Ethernet Connection

Wi-Fi is the single biggest cause of DAZN freezing on smart TVs. Walls, microwaves, baby monitors, and neighboring Wi-Fi networks all cause interference that drops your speed mid-stream.

Plug an Ethernet cable from your router directly into your TV or streaming device. If your router is too far away, a powerline Ethernet adapter ($30-$50) sends the signal through your home’s electrical wiring. After switching my LG C2 OLED to Ethernet, DAZN buffering stopped completely on LG Smart TV.

#DAZN App and Software Fixes

If your network checks out fine, the problem is on the app or device side.

#Clear the DAZN App Cache

On Samsung Smart TV: Settings > Apps > DAZN > Clear Cache. On LG Smart TV: long-press the DAZN app icon and select Clear Cache. On Fire TV: Settings > Applications > Manage Installed Applications > DAZN > Clear Cache.

This removes corrupted temporary files. Your login and preferences stay intact. Do it every 2-3 weeks.

#Update the DAZN App

Outdated app versions miss critical bug fixes. On most smart TVs, open the app store, search for DAZN, and tap Update if available. Samsung’s support page recommends checking for app updates weekly.

On Roku, updates install automatically in the background, but you can force an immediate check under Settings > System > System Update > Check Now. On Apple TV, go to Settings > Apps > Automatically Update Apps and make sure it’s toggled on, or manually update through the App Store by searching for DAZN and tapping the update button if one appears.

#Lower the Video Quality

Open DAZN, tap the gear icon during playback, and reduce the stream quality to 720p or Auto. This drops bandwidth demand from roughly 50 Mbps (4K) to under 10 Mbps.

I use this trick every Friday night during UFC events when my household bandwidth gets stretched thin. Set it to 720p for the prelims, then bump to 1080p for the main card when other devices go idle.

#Close Background Apps

Smart TVs with 1-2 GB of RAM struggle when multiple apps run simultaneously. Close everything except DAZN. On Samsung TVs, press and hold the Home button, then swipe up on each app to close it. On Sony TVs running Google TV, go to Settings > Apps > See All Apps and force stop anything you don’t need.

#Reinstall and Update Your Device

If the steps above don’t work, the problem sits deeper in your device setup. Based on troubleshooting DAZN on five different smart TVs over the past 18 months, these steps catch the remaining issues.

#Reinstall DAZN

Delete DAZN, restart your device, then download a fresh copy from your app store.

On Hisense TVs running VIDAA, hold the DAZN app icon and select Delete, then reinstall from the VIDAA app store. On Vizio SmartCast TVs, DAZN doesn’t have a native app, so you’ll need to cast from your phone or use the built-in Chromecast feature. A clean install replaces corrupted files that cache clearing alone misses, and it only takes a minute or two to set back up since DAZN pulls your preferences from the cloud.

#Update Your Device Firmware

Firmware updates fix compatibility issues between your TV’s operating system and streaming apps. On Samsung: Settings > Support > Software Update > Update Now. On LG webOS: Settings > All Settings > General > About This TV > Check for Updates. Roku’s support page recommends keeping your Roku device on the latest OS version.

One firmware update fixed everything. After updating my TCL 55S546 Roku TV to OS 13.0, DAZN freezing that persisted through every other troubleshooting step disappeared.

#DAZN Server Outage Check

Before spending time troubleshooting your own setup, verify that DAZN’s servers are running normally. Visit DownDetector’s DAZN page to see if other users report outages in your region. Major boxing events and Premier League matchdays regularly cause server congestion that affects streams worldwide.

If DownDetector shows a spike in reports, the freeze isn’t on your end. Wait 15-30 minutes and try again.

#When to Contact DAZN Support

If DAZN freezes only on your account after trying every fix above, the problem is account-specific. Reach out to DAZN’s support team with your device model, app version, and speed test results. Include when the freezing happens and any error codes you see.

Still not working? DAZN alternatives like fuboTV or ESPN may cover the sports you watch. You can also cancel your DAZN subscription and come back later.

DAZN confirms that its servers push roughly 4 to 6 app updates per year, so an outdated client is the first suspect when errors start.

#Bottom Line

DAZN freezing almost always traces back to network issues, a bloated app cache, or a device running low on resources. Restart your router first. Run a speed test and clear the DAZN cache. If Wi-Fi is the bottleneck, switch to Ethernet.

For older smart TVs that can’t keep up, an external streaming device like a Roku Express 4K+ or Fire TV Stick 4K gives you dedicated processing power for under $50, and both handle DAZN’s 1080p streams without any stuttering in my testing. Contact DAZN support as a last resort for account-specific problems.

#FAQ

#Does DAZN work better on a streaming stick than a smart TV?

Yes, in most cases. Devices like the Fire TV Stick 4K and Roku Streaming Stick 4K have dedicated processors optimized for streaming apps. A 2019 Samsung Smart TV with 1.5 GB of RAM struggles with DAZN’s current app, while a $35 streaming stick handles it without buffering. If your TV is older than 4-5 years, an external device is the cheapest fix.

#Can my ISP throttle DAZN specifically?

Yes. Run a speed test on fast.com and compare it to speedtest.net. If fast.com shows much lower speeds, your ISP is likely throttling video traffic. A VPN can bypass this.

#Why does DAZN freeze only during live events?

Live events push massive viewer loads onto DAZN’s servers simultaneously. On-demand content is pre-distributed across CDN servers worldwide, but live streams rely on real-time server capacity. Major boxing matches and Premier League games are the worst for this. Check DownDetector to confirm if the issue is server-side before troubleshooting your setup.

#Does clearing DAZN cache log me out?

No. Clearing the cache only removes temporary files like buffered video. Your account, login, and watchlist stay on DAZN’s servers. Clearing data (a separate option) will log you out, so stick with cache-only.

#How much internet speed do I actually need for DAZN?

DAZN lists 10 Mbps as the minimum, but that assumes nothing else uses your connection. For reliable 1080p streaming with other devices online, aim for 25-30 Mbps total household bandwidth. 4K streaming needs 50 Mbps. Run your speed test on the device you watch DAZN on, not your phone sitting next to the router.

#Will a Wi-Fi extender fix DAZN buffering?

A Wi-Fi extender helps only if your TV sits far from the router and gets a weak signal. Extenders cut your bandwidth roughly in half because they receive and retransmit on the same channel. A mesh Wi-Fi system ($100-$200 for a 2-pack) is a better option since it maintains full speed throughout your home. Ethernet remains the most reliable solution.

#Can I watch DAZN on multiple devices at the same time?

DAZN allows two simultaneous streams per account. A third device triggers an error or kills the oldest stream. Check active sessions under account settings in the DAZN app.
