SMTP Setup

I have a hosted Supabase instance and i am failing to set my SMTP client.
I am using Netcup as server.
I checked the settings a dozent times and they are also working on local as well of my selfhosted instance - but not on the histed one.
The logs are not rly helpful, they just state
\"error\":\"535 5.7.8 Error: authentication failed: authentication failure\",\"level\":\"error\"
\"error\":\"535 5.7.8 Error: authentication failed: authentication failure\",\"level\":\"error\"


Are there anywhere more specific logs?
Are there known issues with Netcup?

I am rly stuck here and kinda confused how this, literally setting some configs, be so difficult.
