I can't be the only Cary Audio DMS-600 user experiencing this problem streaming Qobuz ...

I have a DMS-600 and ever since they came out with the Cary Streamer 2.0 app, I am having all sorts of problems.  I primarily stream Tidal and Spotify.  I have reset everything multiple times with no luck.  My internet connection is rock solid.  Some days I have to log out and relog in to Tidal/Spotify in order to use the app.  Then the music will stop after a period of time, 40 minutes, 1 hour, 1-1/2 hours, etc... There is no specific time period.  I have even lost total control after playing the unit for 2 hours and had to reset the unit again.  For 3 years, I have had no problems whatsoever.  Cary develops a new app and all I have is problems.  Cary even admits they are not an IT expert, so they cannot provide any guidance when it comes to modems etc..  It is very frustrating and I am thinking of buying another brand of music streamer if I cannot solve the problem.  Cary is giving me suggestions, but that is all they are able/willing to do.  It is not their problem and I have been told that I am the only person having this problem.

@vpm, It sounds like the new Cary App is causing these streaming issues and I am surprised they have not been able to help. I still do not understand why you and only one other person are having these issues using the Cary Audio DMS-600. You would think many more Cary users would have these issues. It sounds like the issue is caused by the Cary Streamer 2.0 app and I suggest you contact them again for assistance.

Please also double check the settings in the Streamer 2.0 app to ensure everything is set correctly. Something might of been changed during the update.

IMPORTANT-1: I also found these instructions on the Cary website:

"Updating Firmware
These are big changes to the firmware. After you have successfully updated the firmware, it is highly recommended to then do a Factory Reset from the handheld IR remote (Menu>>Reset). Once the factory reset is complete and your unit has booted up, pull the power cord and leave it UNPLUGGED for 5 minutes. Plug it back in and wait 2 minutes before turning the unit on again.

NOTE: You will have to reconnect to Wi-Fi (if you use Wi-Fi instead of ethernet) and your music streaming services. Additionally, any USB, SD, or PC Share drives will need to rescan".

VERY IMPORTANT-2:  "After you have done the update and Factory Reset of your DMS/AiOS, completely DELETE the Cary Streamer app from your phone or tablet then download the latest app called Cary Streamer 2.0. This new app REQUIRES you have location service turned on while using the app".

I also suggest you contact the Retailer where you purchased your Cary Audio DMS-600. I am hoping they can help.

Many years ago, I also had similar streaming issues and it was caused my Linksys router. The Linksys software/firmware had an issue and was dropping packets. It was a known issue and they were working on a solution. In any case, I replaced my router and my streaming worked perfectly. In your case, I do not know if the router is the cause but it might be worth some investigation.

Any updates on the Cary Audio DMS-600 streaming issues?   Were you able to get it to work?   Please keep us posted.  Thanks......

The problem still exists.  Everything you have mentioned has been recommended by the engineers at Cary Audio.  The latest is I removed the apps from my 2 controllers, I completely reset my router/modem/gateway; Zyxel Model # EMG3415-B10A, my 16 port gigabit switch, and my access point.  I then went into my DMS-600 and reset the network settings, then performed a factory rest.  Unplugged the unit after boot up for 5 minutes.  Replugged in and waited 2 minutes to power up.  Then only reinstalled the Cary App on my I-Phone 8 as it has the latest software version at 14.5.1.  Everything played fine for 2 days and then on the 3rd day Tidal stopped after 32 minutes and then stopped another hour later. 

The Cary Engineers performed their test on a DMS-600 with my log in information to Spotify and did not experience any problems.  My problem is primarily with Tidal.
So where does that leave me.  Cary sells their products direct in the US so I have to deal with the Sales Manager directly.  He found a Technical support article on the Cambridge Audio website which suggests establishing a Static IP address specifically for the DMS-600 to the Cloudflare public DNS server.  This is offered only as a suggestion and not a confirmed resolution.
My problem is I am having a problem finding an IT guy to help me test this change in my ISP's supplied Gateway/Router/Modem.  It can be done, but the Cincinnati Bell Service Technician that came out last week does not know how to do it.  My AV dealer wants me to purchase a new Luxul XWR3150 router for $425 and then just use the ISP Zyxel unit as a modem.  They would do the installation and set up, but they are not guaranteeing me a resolution with Tidal either.
If anyone has experience with the Zyxel EMG3415-B10A unit and can help me, please reply.  I have gone through the 200 page owner's manual multiple times, and while I am getting close, I am still stumped in one key area of where to input the CloudFlare information.  I have the admin password and can make the changes to my current unit, but the way the information is displayed, it is not as easy to follow as on some other routers.
The suggested solution is by going through a public DNS server, it will be quicker than the ISP servers and the information packets from Tidal would be processed quicker.  Tidal plays fine on my Sonos S2 app, so I still think it is the Cary 2.0 app.  I asked is upgrading to the DMS-700 would help, or if DMS-700 customers were having this problem, but was told by the Sales Manager that he did not feel upgrading would help in my situation.  He never really answered my questions.  All I can still say is I had no problems whatsoever for 3 years until Cary changed to the 2.0 Streamer App.

This makes no sense. You said “Everything played fine for 2 days and then on the 3rd day Tidal stopped after 32 minutes and then stopped another hour later”. Why does it play perfectly for 2 days and then stop on the next day?

Since it worked on the previous version, and not the Cary 2.0 App, implies the issue is with the 2.0 version. However, since it worked for 2 days, and then not work the next is a concern. When software works, it ‘usually’ works all the time and not for 2 days and then not. I have no clue what could be causing this. I am also surprised that Cary cannot help solve the issue.

Is it possible your router sometimes has failures that is causing the issue? Can you borrow another router and test it? BTW, several years ago, I was using an Apple Extreme router that sometimes had streaming issues. I replaced it with a Luxul 3100 router and everything worked.

I am not a fan of using the suggested solution of going through a public DNS server.

I hope someone else can solve this issue. Help?
