Updating Google Home connection

this is what has happened.

I've had HA running for about five years. my ISP changed and now I am behind a cgnat.
I put everything under tailscale and everything is fine accessing from my phone etc.

HA runs under synology VMM . I use synology DNS for local names
Google Home Can No longer access or sync with HA, because I no longer have a static IP and I don't longer have an external DDNS set up. I'm trying to set up tailscale funnel to do this instead

I got the tail scale app under HA, and linked to homeassistant.x.ts.net
I can see it under my machines

I went to update the Google Home.

Updated all the domain names

I saved but it is listed as draft

AI says I don't have to certify and deploy this. Is it true?

I went to my phone to the Google home app. I unlinked the [test] project. I went to link it again.

I could see the oauth is using the old URL and not the new one.
so I'm not able to link it again

I tried to proceed with the testing but it would not work.

I'm not sure whether I should be using
homeassistant.x.ts.net
or
homeassistant.x.ts.net:8123

in all the authorization Urls

currently I can access the login screen using homeassistant.x.ts.net:8123

AI tells me that's because I'm on my home network and I'm accessing the machine directly using tailscale Network

Neither am i, but you are aware that your " Url's in the screenshots are HTTPS
And all the urls you are trying to use (post here) Are using HTTP

I don't know i'm assuming the browser will try both but anyway eventually got it working on

homeassistant.x.ts.net

so I believe this means the tail scale tunnel funnel thing is working

but I still cannot do the Google

the problem is now that in my Google Home app on my phone, I have unlinked the test project.

when I try to relink the test project it is using my old URL for login. Of course this does not work anymore so I cannot link the project to my Google Home anymore

I’m not sure where this is set

Try to delete the Cache in Google Home APP and ALSO Google Play APP on your phone i.e Under APPS, and ofcause your Browsers Cache on the Phone

Im definitely Not a big fan of using Mobile apps, and in specific not when doing admin work on servers … I assume you have also tried to use another PC/Laptop, to “exclude” your Phone/Phone apps as the cause

delete the Cache in Google Home APP and ALSO Google Play APP but it’s still the same

maybe the project isn’t working properly in the dev side then?

I went around the houses this week with this having migrated HA from Supervised to Container. I lost hours and then it was suggested to forget it and use this matter hub addon/container instead. 30 mins later and all of my HA devices are in GH and responding quicker than ever. I can even converse with Gemini on my minis about if things are on/off open/closed and then ask for an action and check that action happened.
