What are the steps to reproduce the issue?
Hello R2 I added the wrong domain name and the site is now giving 404 error. although I deleted the domain name, the site is still not active. how can I solve this?
At the moment I’m seeing a 503 error when going to the domain above you have shared with us.
Most likely what happened is that you added the R2 custom domain record with a name that was already in use by a different DNS record. If this was the case, once the custom domain for R2 was added, the previous DNS record would get deleted and replaced with the record needed for R2. You would have to re-add the previous DNS record that was in place before the R2 custom domain was added so that the DNS resolves correctly.
