Nest Integration Not Working / Creating subscription failing

[remy]

The problem

I've been trying to get Google Nest working. I've got everything set up (I've been through the delete credentials many times and recycled) and I'm finally at the point where I get past link account. However, once that happens, I get this error:

(not sure if my project id should be hidden or not, but it's definitely the right project id).

I've seen a similar issue mentioned in this issue - where it's the creation of the subscription that's failing.

This is the logs after a fresh reboot:

I'm seeing similar errors in google's logging, where the log errors referring to the topic that's mentioned in the log earlier:

Resource not found (resource=enterprise-4bd8fa4a-958e-47a0-a945-42d83888f55c)

I don't have an adblockers on my network (which the other thread mentions), but I'm not sure about ipv6 (I'm not sure how to check, though I'm fairly technical competent).

The final result is the entity isn't created.

Thank you for the detail and explaining what you've tried already.

Do you have multiple google cloud project ids? The main reason I can think of is if there is a mismatch between the device access console and the google cloud console (e.g. device access console points to an old oauth client id)

[allenporter]

I'm wondering if the google cloud console doesn't have access to update the topic in the device access console "'projects/sdm-prod/topics/enterprise-4bd8fa4a-958e-47a0-a945-42d83888f55c'" because there is a link between the device access console and the cloud oauth client id

Double check the pubsub topic is enabled and matches what is in the log

[remy]

Oh wow, it's taken me weeks to get here, and yep - that was it. The pub/sub topic in the device access console was disabled. (I'd gone back and forth so many times that I had remove the old oauth client id and it must have removed that at the same time).

FWIW, I originally couldn't get past the oauth screen - turned out that "cleanURLs" extension was rewriting the "unsafe" homeassistant link (that's what took me weeks to solve).

Thank you, that's fixed my particular issue 🙏
