QUIC not working properly on Minecraft Server

What is the name of the domain?

dt2.space

What is the error number?

No Error Number

What is the error message?

ERR Failed to dial a quic connection error=“failed to dial to edge with quic: timeout: handshake did not complete in time”

What is the issue you’re encountering

I think Quic isn’t working?

What steps have you taken to resolve the issue?

Tried to add the port to my firewall, tried to add -protocol http2 / quic onto the registry editor. Pretty new to this. Did block out some ip addresses on the screenshot since I’m not sure what I should show and what I shouldn’t.

What are the steps to reproduce the issue?

running ‘cloudflared tunnel run mc-server’ onto my powershell. I am using Windows 11.

Hi,

Thank you for reaching out to us. The error you’re facing could mean many different things as it could be from network issues, firewalls restrictions, etc. First I would like to ask you to check if your internet is stable and run a speed test https://speed.cloudflare.com/ as this will help identify possible issues before you run the command.

Once this is checked, I would advise you to make sure that no firewall or security application (such anti virus like bitdefender or avast) is blocking QUIC traffic as it uses UDP instead of the usual TCP and may be flagged as suspicious.

It’s also useful to check the version of cloudflared you’re using and always use the updated version: Update cloudflared · Cloudflare Zero Trust docs .

You can also try using this to debug: Tunnel run parameters · Cloudflare Zero Trust docs

I hope this helps solving the issue. Please let us know if you still have questions.
