Same problem. Worked fine this morning!

[seaquake]

Couldn't connect to mine so I tried a factory reset.  I then get a message that it's set up but couldn't connect with my iphone.  Verified local network access was enabled.  Have reset the phone, router, and chromecast; tried a second chromecast, and same message.  Hoping this is related to the verification issues folks are reporting here.

I just used the failed chromecast yesterday for 3 or 4 hours with no problems.

[diaVolo]

[Mario9]

Ive tried unplug 1 minute reboot/reset and nothing. But my other device works? I dont understand what going on? I have 2 and the 1 in livingroom has the problem.

[Jedibart]

My kids informed me this morning that they couldn't cast to any of our 4 TVs with Chromecast. YouTube gave me the "Untrusted device

Family Room TV couldn't be verified. This could be caused by outdated device firmware".

I checked, firmware seems to be is latest on all devices.

Technical information

System firmware version: 275994

Cast firmware: 1.56.275994 - Feb 24th 2025 firmware version

Similar to: Old issue from 2021. So l, I tried performing a factory reset on one of them, and now I can't add it to Google home, gives a "We couldn't authenticate your chromecast" error trying to add it in Google Home app.

Seems to be a cert expiry issue? Maybe to do with the daylight savings time switch last night?

[Varun729]

Same happened with my device 

[Jslnd]

I have exactly the same problem with my device 

[Hongkon]

I have Same issue today. I’ve had the same problem my Kitchen TV couldn't be verified. This could be caused by outdated device firmware

[Svend-Bent]

All my chromecast devices also stopped working half an hour ago with the same message

[Bas3]

I have the exact same problem, with exact the same firmware, it started today. Did a reset also, and can't add the chromecast anymore, saying it can't audenticate. Any solution? Sorry for  bad english, I'm Dutch. 

[diaVolo]

Set the date to Saturday, March 8, 2025 so you can connect it to your Wi-Fi network until they fix the problem.

[PeachesLavelle]

Set the date to march 8th where please?

I had an idea that it might have had something to do with time change occurring yesterday and that Google had to update something— but don’t understand what you meant by set the date back. I have internet connection on my TV, because it shows the google screen saver photos. BUT when I try to use our cell phones or laptop to “cast”television/videos from ANY apps like youtube, tubi, prime etc, it fails to connect. 

[hklions]

For people who did a factory reset, setting your phone's date back to March 8 allows the Google Home app to reconnect to the Chromecast, getting the Chromecast back on the network so it can receive a fix if Google ever gives us one.  It still does not permit casting to the Chromecast.  If you already have the screen saver photos then no need to do this.

[Niks_84]

They need to give you a job at Google! With a nice salary. Provided better support than Google themselves at this point thank you. This worked for me.

Now to play the waiting game with the official fix from them.

[DaleN]

This is a workaround only if you have done a factory reset on your Chromecast and are attempting to reinstall it. 

On your device (phone/tablet) go to your settings for date/time to allow you to manually change the clock on your phone. This will NOT completely solve your problem and may not be necessary depending on what Google puts out as a solution.
