I checked this domain, there really is no CNAME.
DNS server it showed 93 IN A 93 IN A

I use cloudflare’s dns and I have a CNAME record there for “web” pointing at “” how else would be redirecting to

We are still working on it, I think today in the evening there will be additional news.

Thank you Vladimir, all the best on that issue, for the time being I removed the custom domain and now confirmation emails use api.backendless and are working just fine.
I’m glad you replied saying it was an issue and that you are working on it because I ended up thinking it might be a configuration error on my end as your colleague pointed out earlier! (which does not make sense since it stopped working without me changing anything)

Best of luck fixing it!
Have a great day!
