NAT loopback stopped working (RAX30)

I have been happily using my RAX30 to access a server on my home network, but yesterday it stopped working.

 

I can access the service using a local IP address, but when I use its public domain name or my public IP, I get no response.

 

curl says:

 

connect to w.x.y.z port 80 failed: No route to host

 

It is the same on all machine in my house, but when I disconnect my phone from the wifi so it uses mobile data, the server works perfectly.

 

Does anyone have any ideas why?

 

I have tried:

 

* rebooting the router

* unplugging and re-plugging the router

* downgrading the firmware

 

but none of them help.

 

Thanks for your help!

    Of course, as soon as I posted this I found the problem!

     

    NAT loopback was working fine, but the local IP address of my service had changed, so my port forwarding rule was pointing to the wrong IP.

     

    I have added an address reservation under LAN Setup to prevent this happening again.
