I have a Firebase account, and I want to tailor the email address from which verification emails are sent. I follow the instructions.
I have a domain registered with 1&1 and set up as instructed.
But after about 2 days, I get the following.
Please can anyone advise. Thanks
I also was unable to verify my custom domain for the auth templates.
My solution was to remove my custom domain from the host name in the DNS records needed for the verification.
Example:
TXT record: from contoso.com to @
CNAME record: from firebase._domainkey.contoso.com to firebase._domainkey
Note: My domain is hosted by Godaddy.com
For those using Cloudflare. Make sure you don't have DNS flattening activated in the CNAME.
