Answer 1

I had the same problem: 404 error, domain not found.

The cause The EU region selection for the domain on Mailgun

The solution Change the region from EU back to the default of US.

Since I had not used the domain at all up to this point, I simply deleted it, re-added it, then changed my TXT, MX and CNAME records (for example, mailgun.org instead of eu.mailgun.org) at the domain registrar (which was GoDaddy in my case).
