sonos arc error30

I also live in Japan and same situation here. After this unacceptable update all my for speakers (ARC, Sub and 2 SL) gone. Unable to add as a new system and error -30 showed all the time. Tried yesterday 2-3 hours by myself with several devices, 2 routers, wireless and wired...nothing.

Today I tried reaching US support service, after 20 minutes waiting….surprise, surprise it disconnects!!!! Talked to Japanese support and they told me there was a server error ongoing trying to fix it as soon as possible and it was caused by and updated on the app that cause all devices to, guess what, automatically update to the latest firmware. Unbelievable...they update an app and without letting the user know all updates are run with no user consent or at least a notification.

After talking on the phone they told me there is chat available in Australia, I talked to a nice person called Glenn F, we fought for more than 2 hours isolating the issue and although their server issue was still ongoing I was able to finally update Sonos Arc and get back my system with my 2 One SL...but my Sub still shows error -30. So, I have a very beautiful and expensive black box in my living room. Glenn told me to talk to their phone support in Japan for further steps, tried but nothing. They made me install Chrome so I can run a link to gather specific logs on the Sub to make sure there nothing else blocking the update...but because they close at 6pm, they need to finish the call and I had to wait or I can call US phone support...from Japan after 10 pm, I politely asked them to call me as I am the one spending a lot of money but they told me they do not have that service...are you kidding me?????

Do I really need to use a VPN? or send logs or spent hours on the phone on my day off?

Sonos speakers are incredibly good but there software updates/engineering is really something...

Hey there,
Arc just updated itself since the "System Automatic Update" was on. Maybe the server issue got fixed.

somehow my ARC updated. Not sure how.  Sub still refuses to do so though.

I finally managed to update. As a result, both arc and sub are now able to connect.

Did you do anything special?  I've seen people on another forum saying it worked when they used Google's VPN on their phone, but mine didn't (and I have no idea why it would since that VPN doesn't allow region changes)

My speaker setup includes the ARC, ONE, ONE SL, and SUB. I haven't done anything special like using a VPN. Suddenly, I was able to update the ARC from the Android SONOS app. A few hours later, I could update the SUB, and a few hours after that, the HDMI connection with the TV was restored.

Was on live chat for about an hour with Sonos today trying to diagnose why I still get error 30.  They said their techs fixed Japan a couple days back, but the guy said clearly it doesn't seem fixed, so they sent the ticket back in again to have it reexamined

Still error 30, 1000 sub gen 3 .

arc updated like 2days ago. 
 

VPN US didn’t work for sub, this is the third sub from the store 😂. 
Still have some days until return limit.
