Over the weekend break, numerous second-generation Chromecast tools developed into expensive paperweights without caution. Customers required to Reddit to reveal their stress and complication, and a pattern quickly came to be clear: just the second-gen designs were impacted, while very first- and third-gen tools remained to function without a misstep.
Several originally believed Google had actually stopped assistance for the tools, however the search titan has actually made no sign of its intent to quit assistance. Nonetheless, Google has claimed that it knows a concern with Chromecast tools and is dealing with a solution. The source of the problem isn’t clear, however it appears the issue exists with Google and not completion individual; simply put, you could simply need to wait on a server-side solution to turn out.
According to Reddit user u/tchebb, the reason is the expiry of the Chromecast’s gadget verification certification. By excavating with Chrome mistake logs, u/tchebb had the ability to limit a minimum of component of the issue to an intermediate certification authority, or CA. The CA was readied to run out on March 9, 2025– and it appears like it did.

The issue develops when you attempt to cast material to the Chromecast. This causes a mistake message: “Untrusted gadget: [name] could not be confirmed. This can be brought on by obsolete gadget firmware.” The mistake message does not enable you to relocate past that factor; all you can do is liquidate of the dialog box. This apparently occurs with applications like YouTube, and the timing comes with an especially hard time given that several Pixel individuals report display illumination problems given that one of the most current upgrade.
Allow us repeat: This message does not suggest assistance is finishing for Chromecast tools. Also Google has actually verified there is an issue with the second-gen Chromecast and a remedy is currently underway. The business has a background of exterminating tools, however it introduces completion of assistance prior to shutting down solution. Google introduced it would certainly quit sustain the first-gen Chromecast in May 2023, however those tools still function today.
With any kind of good luck, Google will certainly settle the problem and your streaming gadget need to start functioning once more eventually.
