Problem with SRV Record

[enderf5027]

I setted up a A Record for my server minecraft, this record points to my server IP (TLS=auto) and then i setted up a SRV Record (TTL=auto), because i need the connection go on the port 25577. When I try to ping the DNS with the cmd (ping mc.example.com) it return a “Unknown Host” Error.
I tried to change the port of the SRV record from 25577 to 25565 (default port of minecraft servers) and it worked instantly.

Creating DNS Records in Cloudflare for a Minecraft Server

Please select the type of setup you require, on your root domain or on a subdomain

Root domain, e.g. example.com

Add an <a href="https://community.cloudflare.com/t/adding-dns-records/52718">A record</a> for your root domain example.com or @ and point it to the IP address of your Minecraft server. Make sure it is set to as your server won’t work running through Cloudflare’s proxy. <a class="lightbox" href="https://global.discourse-cdn.com/cloudflare…

because i need the connection go on the port

If the record is proxied , I would suggest looking into below article for supported and compatible ports list:

Hi @enderf5027,

SRV records tell specific services, such as Minecraft, to use another host/port when connecting. Ping requests do not honor SRV records - they use the ICMP protocol which does not have a concept of ports (unlike TCP/UDP).

So I’m unsure why an SRV record would prevent pings from succeeding - are you sure nothing else changed?

I already reproduced the steps in the tutorial. Im not using Cloudfare Proxy.
My settings:

I tried to connect with Minecraft too but it didnt found the host (same as Windows Cmd). I asked to a friend to connect and ping the domain and he have the same problem (im using DNS Server 8.8.8.8 and he is using 1.1.1.1)

Please follow the guide suggested by fritexvz

From your screenshot A type obmgang.com is too.
Meaning, goes straight to your origin.
Does mc.obmgang.com exist and can it be resolved at the origin actually and listening over the wanted port (is it open too?), if so?

When i do NSLookup this appears:
Windows 11:

Ubuntu 21.04:

With yougetsignal.com if I try to check the port, it says it’s open.

SRV records work for specific TCP/UDP services only. As I said earlier ping uses ICMP so doesn’t respect SRV records, only A/AAAA records. There is no A/AAAA record for mc.obmgang.com so pings will fail.
