Install nest to home assistant

If any one could help I have tried to install nest with home assistant 100 times with no luck
I followed the video instructions and have managed to get to the home assistant-io wants access to my goole account and it just sits there,home assistant opens with blank screen.
I have checked my email account to make sure it matches, deleted my application credentials and started from scratch several times. Any help would be appreciated

Unfortunately you haven’t given us a lot to go on and right now any suggestions are the equivalent of a guess.

We need a lot more information. There’s a couple nest integrations (builtin and community supported.) so nwe need to know exactly which one you’re trying to set up.

There are no official ‘video instructions’ so did you follow a YouTube tutorial? If so. Which? (please post a link- we need to see your procedure, and with all the changes in Nest Autnh over the last few years your video may just have old instructions)

Finally please post the full exact text of any error message and anything in the logs from the attempts.

The maybe we can help

This is the page I used.

I see they linked MostlyChris’ video into the docs. Nice. You did notice the part up front about Google depricating a bunch of auth types last year (and he didn’t include those in his video on purpose)

How old is your nest account and did you do the steps under deprecated app auth on this page?

Ok in home assistant
Follow the instructions
Add creditionals
Name
OAuth creditionals I’d
OAuth client secret
Enter cloud project I’d
Device access project I’d
Some times get a pop up in home assistant that says google nest.
Can not go further.
Some times I get to the finish but will not load.

Still need this?

My nest account is old.

Yes I did those steps

Still no luck with nest. Anyone with any ideas. Or is it a lost cause

I have gone through the setup several times and I always get a 400 error. I’ve tried changing everything I can find. I’ve created all new projects to get new IDs and I get the same error message every time.

Any help would be appreciated.

This errors usually means you are connecting using the internal url to home assistant.

Are you accessing it thorough your domain ?
