Unable to add custom domain to Google App Engine - URL not found

[rhez]

I'm trying to follow the steps provided by the top answer in

https://stackoverflow.com/questions/49480940/app-engine-custom-domain-with-service

but when I click on the "Add A Custom Domain" button I'm taken to a URL Not Found page

Is anyone else experiencing this problem?

Same here, no solution yet.

Rhez.

Just solved it, go to the page where you add custom domains and simply add /add to the URL and it will send you to the correct page, so this:

https://console.cloud.google.com/appengine/settings/domains/add?project=gtm-xxxxxxx-xxxxx

Remember to edit the gtm-xxxxxx-xxxx to match your project. 

My guess is google messed up the button in some way. 

Good luck!

Got it to work, thanks! Hope the button will be fixed!
