Snappy Mail - Domain not allowed

[RazielKanos]

I'm trying to get Snappy mail running in my Nextcloud
I've set up the domains in the admin dashboard, and when i run a test with my cloudron credentials i get a green light, but when i try to log in via the frontend, it keeps telling me "domain not allowed"

I deleted all other domains, now i am puzzled. Has someone had this issue before?

Hopefully that helps?
