Here is a help page with some troubleshooting steps: Authentication isn't successful - Android - Chromecast Help . See if any of the bullet points there help you get connected.

I have the same issue. I factory reset my CCWGTV and after scanning the QR code on screen using Home, I get the same error as above. I tried multiple times, including ensuring that I was connecting to my 2.4ghz wifi. Please advise

In addition to the help article steps you can also try rebooting your router, Chromecast (again). Toggle on off Bluetooth and wifi on your phone.

Be sure you are using the latest Google Home app.

I have the same issue. I've followed all the suggested steps and continually get the "couldn't authenticate Chromecast" error. When trying manual setup with the remote it fails on 2-step verification saying the code from g.co/SC is invalid.

Hey all,

Tell us what router you have, location and troubleshooting you've done.

I can let our Community Specialists take a look at this. They may know of any known issues etc. that may be contributing to this error message.

My apartment has a mesh router that's provided by the building. I have 0 visibility with this router (it sucks), but it only supports 5GHz. But I think the Chromecast ultra supports both bands, which shouldn't be the issue then. All of my other devices, Pixel 7, macbook pro, iPad, and Alexa devices are connected to the router and working. its just this Chromecast ultra doesn't seem to connect. I talked to the customer service people and we went through all of their debugging activities, including reboots, resets, power cycles, and it still didn't work. So they're going to replace this device. I'll check with that unit and update this thread in a couple of weeks

Thanks I've tried these approaches and still have the same issue. I can manually setup the device, but then it doesn't show up in my Home app. My modem/router is Sagemcom Fast 5250, Virgin Canada.

Hi folks,

Thanks for reaching out and for trying the steps JillG recommended. Could you all try to use another network to set up your Chromecast devices and observe if it will make a difference? Using another phone to set it up will also help us further isolate the issue.

Thanks for the help here, JillG

Regards,

Juni

I tried using and iPhone, got further, but still failed. I was able to accept the terms, see my AP, select it, enter the pw. Then it displayed Connected, then went to a screen that said something went wrong. This is further than I got with my Pixel 7.

How am I supposed to use another network?

As mentioned, I can setup the device manually, but it doesn't appear in my Home if I do that. If you have a procedure whereby I could add it to Home after setup I can avoid all of this.

I've got Google Wifi (AC-1304) mesh. The device I'm having an issue with is a Chromecast with Google TV. It's been working fine for months and after a recent Google password change I assumed it wanted to reauthenticate, but it failed when doing the second step of 2-step authentication. I think did a factory rest to of the Chromecast to see starting over helped. Doing the setup in the Home app (on a Pixel 6 Pro) it failed with the message in the original post. I then tried manual setup and it fails on 2-step authentication always saying the code from g.co/sc is invalid. I don't think I previously I'd had to do 2-step verification that way so maybe the issue has something to do with Googles recent switch/update of phone security keys to passkeys? I've also tried doing a manual setup with my phone hotspot as the wifi device and it failed in the same way.

The same problem after factory reset of Chromecast TV.

I can't believe that there are so many people with the same problems in the last few days, nobody actually came with any solution to it and this so called support is silent about that.

I want to return the product to Google, they can keep it even they couldn't authenticate my Chromecast.

Gosh 🤦🏻‍♂️

Re: We couldn't authenticate

I've now also tested setting up my Chromecast with the Home app on another Android phone and with the Home app on a Chromebook and had the same failure.

Re: We couldn't authenticate

I'm having this issue as well. CCWGT was factory reset to remove my account when i gave it to my in-laws. During setup it would allow scanning of the QR code and tv would say connected, "finish setup in the Google home app." Google home app would spin for a moment and show the message, "we were unable to authenticate your chromecast"

I factory reset again and tried manual setup with same failure. During Google account login received error before typing in password that said something about failure to transport. FDR again and same results.

I brought it back home and tried to just sign in with my account like it was before and the same errors came up. I've reset it a couple of more times and checked for app updates, cleared app cache, tried multiple routers, Android phones and Google accounts now all with the same result.

I'm using the public preview version of the app on a Samsung s22 ultra.

I'm having the same issue. Using the scanner on my phone I could not authenticate my Chromecast. I could install it manually with no problem. Can't sync my TV nor do I have Chromecast in my Google home app. I'm using T-Mobile 5G gateway. Samsung S22+

Well, after following all suggested steps from Google support I just gave up, deleted the home app and I connected the Chromecast TV manually.

Don't expect any racional explanation of this from Google, it's obviously their mess of home app data architecture.

Re: We couldn't authenticate

Mikeinstlouis — Tue, 20 Jun 2023 03:02:46 GMT

I have read that the cause of this problem was because of the network. Well it would not work on my T-Mobile 5G gateway so what I did was I unplugged that, and replugged in my AT&t before I send it back. I tried to set up the Chromecast through AT&t and it did the same exact thing. It said Chromecast could not be authenticated so I think I pretty much have shown it doesn't have to do with my T-Mobile 5G gateway nor the AT&t. It's a problem with either the Google home app or with Google Chromecast but my bet is with the Google home app.

It looks like our diamond support expert has given up on us.

Well, what a piece of junk.

Same error. Chromecast with Google TV, setting up with a pixel 6 pro on a Nest WiFi Pro network. Can't get more Google than this.

TV says connected, phone says error. If I set up manually I can't add to my Google home.

I hate adding to the electronic waste pile. Thanks Google.
