Connect Server to subdomain
I'd like to connect a subdomain app.domain.de to a DI droplet.
I've asked my domain provider what to do and he said I might just add an A Record for that subdomain and set the IP, but that didn't work.
I will just list my current settings as I'm new to DNS and am not sure if these settings are important to know. I can access my website using www.domain.de and domain.de, it is hosted on Webflow.com
Could you help set the right settings?
