In the past problems like this were reported by players using Microsoft-related email addresses (live. com, outlook. com, hotmail .com, … ). Sometimes the related mail services filter out mails before they even reach the user’s spam folders.
In the past I recommended to use gmail-accounts, as those problems had never been reported by users using those.
However I am able to reproduce the issue with GMail-accounts now, too.
The dice server itself does not return any error.
So maybe it would be a good idea that those users who experience the problem post their mail provider here, so we can probably identify something.
