Unfortunately, I have a problem with my subdomain I wanted to set a redirect to my Minecraft server only for a subdomain only, the problem is the redirect is active on the main domain but not on the subdomain.
Unfortunately, I do not know how or what to set because it works properly.
Hope there's a solution to the problem.
The question how something like that I have already answered you:
In order to forward a subdomain, you also have to create a subdomain, depending on the provider.
SRV record if subdomain is mc.domain.de.
_Service._Protocol.Name IN SRV Priority Weight Port Target
_minecraft._tcp.mc IN SRV 0 5 port ip
