Minecraft SRV record stopped working for some people (including me)

[carbon0]

What is the name of the domain?

carbonatek.uk

What is the issue you’re encountering

Minecraft refuses to connect to a server through a SRV record in Cloudflare.

What steps have you taken to resolve the issue?

Changed DNS from local pihole to 1.1.1.1/1.1.1.2

What feature, service or problem is this related to?

DNS records

What are the steps to reproduce the issue?

Try to connect with a private modpack to carbonatek.uk in Minecraft. The server itself works, typing out the IPv4 address instantly connects, and some people’s connection works fine. Tried flushing the DNS in resolvectl, disabling it, changing DNS, but nothing worked.

Your SRV record points at a proxied DNS record. It must point at a DNS-Only record.

How come it has worked before though?

I have checked now with my friend and he is able to connect, unlike me. So I wonder what exactly is going on that I’m getting “blocked”.

You are pointing your SRV record at a proxied DNS record, which doesn’t make sense.

Your screenshot clearly shows Minecraft connecting at a proxy IP, which can’t work.

I’d guess that different resolvers handle the misconfiguration in different ways, so it works for some but not for others.

But you simply need to fix your DNS configuration. Create a DNS A record with the server IP and point the SRV record to the new A record.

I swear it worked for the last 8 months just fine, with the A record proxied but the SRV record not. People still connect through the proxy, and I just put an A record into /etc/hosts locally.
