Only my.domain.com is resolved

[yyyy]

Only my.domain.com is resolved on my PC and smartphone. In contrast, domain.com and www.domain.com are only resolved on my PC, but not on my smartphone. The latter lead/should lead to my Ghost blog hosted with Cloudron.

What can be done to solve this problem? I am happy about any help

Check the DNS resolution first. Is domain.com and www.domain.com resolving to the correct IP? If it is, then the issue is something related to smartphone or some smartphone network issue.
