Netflix no longer streaming

CloudFlare:

1.1 DNS addresses:

• For IPv4: 1.1. 1.1 and 1.0. 0.1.
• For IPv6: 2606:4700:4700::1111 and 2606:4700:4700::1001

“Cloudflare offers a public DNS resolver that anyone can use by setting their device's DNS to 1.1.1.1 and 1.0.0.1. These are the IPv4 addresses. The IPv6 addresses for this service are 2606:4700:4700::1111 and 2606:4700:4700::1001."

Thanks for all of your help and input on this iTinkeralot! I have my T-Mobile Gateway connected to an Asus ZenWifi mesh system (3 nodes). All of my devices are connected to the Asus mesh wifi network.

That said, I had already tried connecting my devices directly to the gateway and that did not help.  The behavior is the same whether I'm connected directly to the T-Mobile gateway or I am connected to one of my mesh nodes. 

I also tried multiple different DNS providers, including Cloudflare, Google, Quad9 and some others (both connecting directly to the T-Mobile Gateway and via the mesh network). Again, there was no change in behavior regardless of what DNS provider I was using. 

Hum… it sounds like the issue is upstream possibly but not a DNS resolution issue. Given both of you refer to 2/9/2023 as the same date that the behavior started that does seem as if there was some upstream network change responsible for the behavior OR was there possibly a gateway firmware update maybe? I would think T-Mobile might possibly be able to provide some information on that. Well, one would hope so but it is hard to say. 

Given both of you saw the behavior surface on the same date it might be good to see if T-Mobile would provide a different model of the gateway or another to test with. Just thinking. Was firmware revision ever investigated by the T-Mobile support engineers?

Bluesky, which Gateway do you have?

I have a KVD21 gateway and I cannot find any way to resolve this issue. I have spent so many hours trying every combination at home with no luck. I just connected the gateway, with nothing else connected to it, but the TV through wifi, but that still does not work. I have been on the phone for many hours with T-Mobile and Netflix, but they are pointing fingers at each other.

I have 2 options at this point. Go back to Spectrum and the increase of $50 per month or say goodbye to Netflix (for which T-Mobile is paying most of the cost). So frustrating.

I have the same gateway as you do. I worked with Tech Support Andy from California. He was super helpful.

The store clerk had told me if things didn't work right when I disconnected my Wi-Fi router that I should just exchange gateways and start over with a new one.

I know how frustrating it is. If I were you I'd start over with a new one. Good luck!!

Just a quick update... Netflix is now working on one of my devices, a Roku TV. Note that it had stopped working on this device on 2/9 along with all of my other devices. This TV is still going through my Asus mesh network just like the rest of my devices currently are. Also, some time this afternoon Netflix on my Windows laptop and on my iPhone started working correctly (i.e., the thumbnails started showing up). I tried a couple of times earlier in the day, and the thumbnails were still not showing up earlier (even after Netflix started working on my Roku TV.

Netflix is still not working on my Fire TV STBs or my LG TV. I haven't had a chance to see if it works on my Vizio (I don't generally use the built-in Vizio apps)

I suspect that Netflix has started rolling out a fix to this issue, and Roku was the first to get it, followed some time later by iOS and Windows. I'm hopeful that means my other devices will start working soon.

About 5:00 PM yesterday I placed another call with T-Mobile Internet support team. While I was waiting for their callback I tried to use Netflix again. This time all the thumbnails populated. I takes a long time to start a show, but once it starts it plays to the end. I got the same results on all the other TVs. It seems this problem is partially fixed, but bandwidth to Netflix seems to still be an issue. The preview for shows does not appear. So while there is progress, it is still not 100% fixed.

In my case, this issue was caused by the fact that a rep signed me up for a business account…even though I didn't need one and don't own a business. The business accounts, by default, have a "productivity block" on them so employees can't sit around watching tv all day. It took multiple calls, but the latest agent I talked to disabled the block. After a few reboots, of the tv and the Gateway, streaming services are all working now
