Unable to Connect to Minecraft Server via Cloudflare Tunnel (Other Services Working Fine)

Yes, I'm glad it turned out to be a simple fix. I'm also relieved to know that the general steps I followed were correct. Cloudflare's public documentation is really clear and helpful. And yes, I’ll remember that casually using localhost can be risky. Thank you so much for your help.

Unable to Connect to Minecraft Server via Cloudflare Tunnel (Other Services Working Fine)

Thank you. After running the access tcp command on the client machine, I tried connecting from Minecraft to localhost:25555 multiple times, but no logs were output.

PS C:\Users\php> cloudflared access tcp --hostname minecraft.gameserver.kyoto--url localhost:25555 2025-05-02T19:50:34Z INF Start Websocket listener host=localhost:25555

By the way, running the Test-NetConnection command from the client machine also does not produce any logs.

Understood. I’ll provide the output from the command as-is, with only the domain changed. Should the access tcp command be run on the server machine or the client machine? If there’s any documentation for this process, I’d appreciate it if you could share it so I can follow along.

Yes, it's a dummy. This is my first time posting to this open community, so I'm using a fake domain. If the real domain is needed, I can provide it by DM.

Unable to Connect to Minecraft Server via Cloudflare Tunnel (Other Services Working Fine)

Thank you for your reply. I'm sorry for the lack of explanation. Between steps 8 and 9, I performed the following actions on the client machine: On the client machine, I started the tunnel:

PS C:\Users\php> cloudflared access tcp --hostname minecraft.gameserver.kyoto --url localhost:25555 2025-05-02T19:50:34Z INF Start Websocket listener host=localhost:25555

Step 9: Testing from within the local network on a different PC

Step 10: I launched Minecraft Java Edition on the client machine and attempted to connect to localhost:25555, but I received the error: Connection refused: no further information.
