ADT not wanting to reconnect

RAD32 — Sat, 06 Dec 2025 08:27:46 GMT

I used to have ADT synced to my google home but about a month ago I noticed that it quit working. I did a little research and read where it said to unlink the two and link them back together so that’s what I tried to do. After unlinking them I have yet to be able to re link them. Is anyone else having issues? Is there anything I could be doing wrong? Is there a special trick to link the ADT system to Google home that maybe I’m not remembering? Any help would be appreciated

Hi RAD32,

Thanks for reaching out to the community! I understand that your ADT account stopped syncing with your Google Home app about a month ago. Despite trying to re-link the two services, the connection attempt was unsuccessful. I appreciate you taking the time to search for a solution and try to troubleshoot this issue. No worries, I can definitely help you with this!

To better investigate this situation, please provide the following information:

Could you confirm if you received any error messages when you tried to link your Google Account within the ADT app?
Is the Google Account linked to your Google Home app the same one you use for your ADT account?
Have you tried re-linking your apps by using a different mobile device?

In the meantime, I suggest you try the following steps:

Verify that your mobile operating system, the Google Home app, and the ADT app are all running the latest available versions.
Ensure your Google Account is completely unlinked from the ADT app settings.
Sign out of the ADT app.
Uninstall the ADT app from your phone, and then reinstall it.
Open the reinstalled ADT app and link your Google Account one more time. To ensure you’re following the right process, please see this article: Set up ADT with Google.

Let me know how it goes.

Best regards,

Jennniffer

Jennifer:

Also having similar issue with ADT / hub. ADT control was originally installed on new hub purchased 1/8/26 by ADT service tech when alarm was installed. On 1/22/26 with the assistance of ADT we set up the ADT control app on spouse's I Phone. For some reason had to change the password to make the app work. Once that was done the caution icon appeared on the hub screen indicating the hub was trying to connect to ADT. Eventually the icon disappeared and so did the ADT icon. Since then have been on phone with ADT advanced team in attempt to restore the ADT function. After 2 hours and trying everything they could still no ADT function on hub. Receive the following error message every time after performing the last step of logging in on the ADT screen.

"The requested URL was rejected. Your support ID and etc. Error 500 - Internal Server Error

Thank you
