Network Problem Detected

What do you do if you do not have the Cisco App and you are still getting the message “Network Problem Detected”?  #PleaseHelp

I would recommend that you contact Sonos Support directly to discuss it.

I usually suggest the phone folks, they have more tools available because they're on the phone with you, but they are only available Monday through Friday during business hours. Both the Twitter and Facebook support folks are available 24/7.

I am soooooo glad I just had a look at this THANKYOU! I posted a thread a few hours ago after trying to sign in after getting a new android device Here only to be confronted with not being able to sign on, mentioning the DNS request made me realised I had cloud flares 1.1.1.1 app running disabled  the VPN  and BAM  the window loaded first time! This definitely  by what I can see to be a dns problem not sure why it would cause this behaviour  though, I'm no iOS expert but maybe the new update changed network settings? Check and see if you are using a vpn would be my first thought. I will be updating my own post linking to this thread incase it is indeed the same issue that I was having

Talked to Sonos support, although they didn’t find the issue until I came across this thread and saw the comment about Cisco Security Connector. With this information we were able to determine what the issue is as all my Apple devices connect as expected except for my 2 work devices which have the CSC (Cisco Security Connector) installed.

The Sonos Support person did find this bit of info on how to get further resolution from Cisco (unfortunately the iOS upgrade to 13.2.3 didn’t work)… Go to this link for Sonos and the Cisco Security Connector (CSC) for iOS (same link from IanHenry above):

I’m waiting now to hear back from Cisco on this matter.

Just wanted to say that on an iphone X on a network which has ipv6 as well the same issue occured.

When I disabled the ipv6 DNS the message went away

I have been having the same issue--on my iPhone, I could not access any of my music services, nor could I log in to my Sonos account, though I could see all my speakers and start/pause them (but not choose what they would play). After a lengthy back-and-forth with the Sonos support team, and a phone call today, I found this thread and decided to see if I had a VPN going on my phone without my knowledge. Turns out I did--ExpressVPN had activated itself without giving me any indication of it--so I turned it off and all started to work again. 

How frustrating that must have been! My previous company required a ‘profile’ be installed on all devices that could connect to the email servers. What they didn’t explain was that ‘profile’ included a VPN, which took me a while to figure out, so I feel your pain. 

I have the same problem.  I have two Sound 1 speakers playing in stereo. I was controlling them via a Pixel 2 XL. Last week everything worked perfectly. This weekend, all of a sudden certain services are not available on the phone controller. There is a message about signing in but when I try to do so I get a “Network problem detected” message. I have a router for internet and two range extenders, one on each floor of my house. The basement extender is hardwired to the router. The upstairs is linked to the basement extender via wifi. I have rebooted everything - router, extenders, speakers, phone. I still get the message. I can easily control the speakers from the controller on my laptop, including insuring I am signed in there. All services are available on the laptop controller. But on the phone, no luck. However, when I  change stations from the laptop controller, the change is reflected on my phone. Any help appreciated. 

@snitramc sounds a lot like you had a VPN added to your phone, maybe to connect to your work network so you can work remotely? VPNs will usually mess with local network access.

As everything works from your laptop, the problem is on your phone somewhere.

Hi,

i have read through the whole of this topic as I had exactly the same problem causing me no end of confusion. Then I saw the dreaded VPN word and realised this was what was causing the issue.

i use Norton secure VPN. Norton keep telling me to enable it so I did but it causes a LOT of issues with many apps including my sonos.

so, what’s the point of personal VPN on my iPad if it causes apps to fail or not work properly?

thanks to all in this forum for solving my issue quicker than I would have otherwise.
