I’m hoping someone can help me figure out what I’m doing wrong.
I have a VM on my local network that has Traefik, 2 apps (whomai and myapp), and wireguard in server mode (let’s call this VM “server”). I have another VM on the same network with Traefik and wireguard in client mode (let’s call this VM “client”).
- both VMs can can ping each other using their VPN IP addresses
- wireguard successfully handshakes
- I have
myapp.mydomain.com
as a host override on my router so every computer in my house points it to “client” - when I run
curl -L --header 'Host: myapp.mydomain.com'
from the myapp container it successfully returns the myapp page.
But when I browse to http://myapp.mydomain.com
I get “Internal Server Error”, yet nothing appears in the docker logs for any app (neither traefik container, neither wireguard container, nor the myapp container).
Any suggestions/assistance would be appreciated!
Thanks so much for helping me troubleshoot this, @lemmyvore@feddit.nl!
My browser was using DoH, but I turned it off and still have the same issue.
Yes, running
curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51
on the laptop results in “Internal Server Error”.ping whoami.mydomain.com
hits 192.168.1.51.From the router:
Shell Output - curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0- 100 17 100 17 0 0 8200 0 --:--:-- --:--:-- --:--:-- 17000 100 21 100 21 0 0 649 0 --:--:-- --:--:-- --:--:-- 649 Internal Server Error
From the wireguard client container on the “client” VM:
curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 Internal Server Error
From the traefik container on the “client” VM:
$ curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 Internal Server Error
From the “client” VM itself:
# curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 Internal Server Error
From the wireguard container on the “server” VM:
# curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 Internal Server Error
From the traefik container on the “server” VM (This is interesting. Why can’t I ping from this traefik installation but a can from the other? But even though it won’t ping, it did resolve to the correct IP):
$ ping whoami.mydomain.com PING whoami.mydomain.com (192.168.1.51): 56 data bytes ping: permission denied (are you root?)
From the “server” VM itself:
# curl -L -k --header 'Host: whoami.mydomain.com' 192.168.1.51 Internal Server Error
Also, just to make sure the app is indeed running, I curled it from it’s own container (I’m using myapp here instead of whoami, because whoami doesn’t have a shell):
# curl -L -k --header 'Host: myapp.mydomain.com' localhost:8080 `` `` `` `` ... ...
So the app is up and running.
