  • Hey man, so I’ve been thinking about this and doing a lot of reading since I read your comment… Question: what makes an SSH tunnel any more secure than an SSL connection through a browser? I only have port 443 opened on my home network for reverse proxy and wouldn’t want to open anything more to the internet. Am I missing something fundamental in terms of security? I would definitely like to understand this more.












  • OMG I figured it out. It was actually my last comment that got me thinking in the right direction. The problem was that I was using the EC2 public IP address to point the tunnel to. EC2 also has an internal private IP address. Switched the tunnel to point to that, and it works! I felt like such a dummy when I thought about it. The tunnel is trying to hit the app internally. Why would it need to go out to the internet and retrieve a firewalled public address? Seems so obvious now.


  • Not yet. I did a fresh install on a new EC2 server. Cloudflare tunnel seems to be connected correctly i.e. the handshake is successful, and when I hit the URL, I get the cloudflare 404 page that shows the app is down. @lilshalom (is that how you tag in Lemmy?) I’m having trouble figuring out EC2 logs - I’m pretty new to AWS. But I’m pretty confident at this point that the tunnel is setup correctly, but for some reason, it cannot connect to the app. For what it’s worth, I did have it all working on my local raspberry pi. I’ll tinker a bit more and then I’ll probably try the app’s GitHub issues page and see if the dev can chime in


  • Yep all outbound ports are opened, per default. Tunnel does show as healthy in the dashboard. The cloudflared logs say the tunnel is established correctly but cloudflared cannot reach the application. I only have my home IP address set on inbound for both ssh as well as the application and port I’m trying to access. I’ll look into this into more detail again in a couple hours and look at your and lilshalom’s suggestions
