1. The problem I’m having: Within my local network, I cannot access any of my services via URL. If I use the local IP, I can. For example pics.smithbury.com fails but 192.168.1.118:2283 works. I can access the services via mobile device, not connected to local network. A complication to this is I h…

Deleting the referenced decision using cli, that resolved my issue. Appears to be a CrowdSec problem rather than a Caddy one.

Thanks for the info. I’ve stood up pihole with unbound but still intermittently getting the issue previously described and intermittently unable to access from external networks via URL either. Trying to curl from Caddy host to a hosted service: $ curl https://vik.smithbury.com curl: (28) Failed t…

When troubleshooting, try using -v with curl. It provides extra info that might be helpful. You can also run: sudo ss -tulpn to see what’s currently listening on the Caddy host.

It’s come good again overnight. What’s odd is I can see my WAN IP and Cloudflare DNS records haven’t changed in that time. I’ll try those commands and share the output next time it happens. It’s usually a couple times a week.

Tested tonight when the issue recurred. $ curl -v https://ab.smithbury.com * Trying 118.210.34.26:443... * connect to 118.210.34.26 port 443 failed: Connection timed out * Failed to connect to ab.smithbury.com port 443 after 130854 ms: Connection timed out * Closing connection 0 curl: (28) Failed…

Sites are accessible externally, but not on the internal network Help

This is typically because your router at the edge of your network doesn’t support NAT hairpinning: The usual solution is to run a DNS server inside of your LAN which resolves your domains to the LAN IP of your server for machines inside your network, and still resolves via public DNS to your WAN IP.

Cannot connect to application using duckdns Help

@TheRettom has already given you a great answer. Since you didn’t provide much detail about how your home network connects to the internet - specifically whether your Ubuntu server is also your router or if you have a separate SOHO router - I’ll assume the latter. The feature you’re looking for is called NAT Loopback, also known as Hairpin NAT or NAT Reflection. This allows devices inside your local network to access a service using the public IP (or a domain name resolving to it). Without NAT…

Using Caddy as a reverse proxy in a home network Wiki

If you want to run a service inside a Local Area Network (LAN) such as your home or office – and especially if you want to be able to access it from outside that network – Caddy can help you accomplish this quite easily. This guide will show you how. It assumes you’ve never done this before, but that you have some technical proficiency and are somewhat knowledgable about your own network. Do this at your own risk. There are several ways to make private services accessible from other n…
