SSH tunnel returns a blank page

[ericjorg]

I’m new to CloudFlare, trying to get an SSH tunnel to work. Here is my setup:

Rasberry Pi on my home network is hosting a website on port 8080 and rpi is configured to route port 80 traffic to 8080. When I hit my rpi on port 80 from my local machine, the web site serves up just fine.

My rpi is running tunneling as a service with this config file:

    tunnel: 22033c31-092f-47a7-ab5b-3156ad3a5a5a
    credentials-file: /home/pi/.cloudflared/22033c31-092f-47a7-ab5b-3156ad3a5a5a.json

    ingress:
      - hostname: clusterfun.tv
        service: ssh://localhost:22
      - service: http_status:404

When I hit clusterfun.tv on port 80, I just get a blank page. I must be missing something - maybe a command to route web traffic?

What are you expecting to see? Your Ingress rule routes that hostname to SSH, not a website. If you want to use that hostname for the SSH web interface, you need to enable the Access setting for that:

I’m expecting to see whatever my rpi is dishing out on port 80. I’m not sure where to activate that setting from my cloudflare dashboard. Where do I find it?

Side question: should I expect websockets to work through the ssh tunnel?

dishing out on port 80

Not if Cloudflare DNS for that hostname is a CNAME that points to the Cloudflare Tunnel. That hostname tunnel leads to Port 22 on your Pi.

Sweet, I changed the service to point to http://localhost:8080 and it worked!

Looks like the next thing I need to figure out is how to get websockets to work over https. It’s probably something I’m doing wrong in the code.

how to get websockets to work over https

Regarding websockets and domain being proxied via Cloudflare, maybe below topics could help a bit:

WSS loaded all day today, now barely loading at all? EHOSTUNREACH

Been testing a lot today and finding that I am now being limited severely, not impressed at all; no warnings nothing. Odd though, my HTTPs too the same amount of requests and that hasn’t been limited yet. Is anyone familiar with this as to why my WSS would be blocked and not my HTTPs?

Protocol WSS to WS does work in CloudFlare?

Hi, there! My SSL/TLS encryption mode is Flexible Can I use WebSocket, if in my server WebSocket protocol is running under plain WS at port 8443. At CloudFlare side is WSS and port is 8443. Or I must use in all over side WSS protocols?

My problem was that I needed to change the prefix from ws to wss for the secure version of my page. Amazingly, websockets just work!
