custom domain on cloudflair was verified, then stopped being verified

I've added the credentials as instructed by the appwrite documentation, with cname set to dns only without proxy, and it successfully validated my domain, and was deploying to that domain. Today I had to change the project name in the console settings, and added my domain to the web app platform in the overview panel, and I don't know if this is related, or if it was something else, but now appwrite can't verify my domain, and new deployments go to the appwrite provided domain instead of my custom domain. I haven't changed anything in the cloudflair configuration, nor the appwrite custom domain configuration. Appwrite offered to add ns credentials to cloudflair as a troubleshooting step, but verification still failed. Can you please help me figure out what's going on?
