Error 1066

Oddly, there is nothing in the FAQ database about this error. I would suggest you try a couple of things first. Temporarily wire the speaker to your router with an Ethernet cable, and try again. It also might be worth rebooting the router, sometimes updates get pushed to the router without our knowledge, and may get ‘stuck’. Finally, I’d call Sonos Support directly to discuss it.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Translation:

Curieusement, il n'y a rien dans la base de données FAQ à propos de cette erreur. Je vous suggère d'essayer d'abord quelques choses. Câblez temporairement le haut-parleur à votre routeur à l'aide d'un câble Ethernet, puis réessayez. Cela pourrait également valoir la peine de redémarrer le routeur, parfois les mises à jour sont poussées sur le routeur à notre insu, et peuvent être "bloquées". Enfin, j'appellerais directement le support Sonos pour en discuter.

Lorsque vous parlez directement aux gens du téléphone, ils disposent d'outils qui leur permettront de vous donner des conseils spécifiques à votre réseau et à votre système Sonos.

Thanks Bruce,
I tried connecting the speaker via RJ45 and restarting my router, but the same problem still occurs. Phone support opens tomorrow, I'll try that.

You know, there might be one more thing to check for. Depending on, of course, what that error ‘really’ means. 

You might check for any port blocking software. VPNs, virus protection, work profiles, pretty much anything that might be stopping the system from reaching the update servers. But I suspect your best bet would be the phone call. They’re much more likely to speak your language, and help, than I can. 

I have the exact same error that started today so there might be a problem on the Sonos side. 

I’m not adding any speakers today, so I’m not experiencing this, but if you think it might be a software issue, the best thing to do is to call Sonos Support directly to discuss it. The more hard evidence they can pass back to the coders, the better. Or, if it’s a local issue, the easier it becomes to ‘fix’ it. 

And, for that matter, the quicker they might add an FAQ article to explain what 1066 is, and perhaps how to ‘fix’ it. ;)

Type “Sonos Error 1066 in browser and search. There’s an AI breakdown. Don’t have time to C/P the response.

Interestingly, I needed to add a pair of Era 100s today. On the first device, I received this error. On the second time through, I was successful, even without ‘rebooting’ the speaker. On the second device, I did not receive the error, and had no trouble at all. I submitted diagnostics, on the offhand chance it might help Sonos track down why it errored on the first, but not on the subsequent attempt, nor the second device.

Hi, 

I have the same 1066 error on my Sonos move 2. Reason is that I wanted to update the firmware to be able to use Google voice. I really had it with the Sonos voice. And since I use Ytmusic, I really want Google assistant. Sonos voice does not even support Ytmusic.

I tried resetting the move 2 mqny times, changing network, resetting router...nothing helps
