Minecraft behind cloudflare tunnel - getsockopt error
Hi everyone!
As the title says, I'm trying to run a minecraft server behind a cloudflare tunnel. By default, I have a several self-hosted services running and functioning properly, with tunnel login page for specific e-mails. Now I'm trying to run a minecraft server with bypass policy, but I get a "getsockopt" error when trying to connect to it. What should I check? Please help, I'm lost and confused. :/

Cloudflare Tunnels use Cloudflare's proxy, which only supports proxying HTTP Traffic. If you want to use non-http applications over your tunnel, Cloudflare has a few other options:
For a few specific protocols such as SSH, RDP, and SMB, Cloudflare has guides for them here:
https://developers.cloudflare.com/cloudflare-one/applications/non-http/
For Arbitrary TCP like Minecraft, MySQL, and any other tcp application, Cloudflare has a guide here: https://developers.cloudflare.com/cloudflare-one/applications/non-http/arbitrary-tcp/
For Arbitrary UDP like Minecraft Bedrock, SMTP, and any other udp application, you will need to use Private Networking with WARP: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/private-net/connect-private-networks/
Please note for all of these except SSH and VNC which can be browser-rendered, you will either need to use cloudflared (Cloudflare's tunnel daemon) on the client machine running in the background or Private Networking with WARP, and have WARP installed on the client machine logged into your Zero Trust Team.
So basically, if I want to run it with tunnel, every user that wants to connect to my server has to configure his own cloudflared connector?
Yup, though I believe there is a mod that will do it for you too
Don’t remember the name off the top of my head tho
Oh, cool, I'll try to look it up, thanks 🙂
