Seeking assistance setting up traefik with wireguard server
Seeking assistance setting up traefik with wireguard server
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.comas 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!
You'll have to give more details. Where are you browsing from? How is the tunnel between the VMs relevant? Are the VMs' IPs routed on the LAN? Is
myapp.mydomain.comdefined in a DNS server, and if so which? Is it the DNS server on the LAN or a public DNS? Do both VM and the machine you're browsing from resolve that address to the same IP, and is that IP reachable from the browser machine?Thanks for helping, @[email protected].
I'm browsing from my laptop on the same network as promox: 192.168.1.0/24
The tunnel is relevant in that my ultimate goal will be to have "client" in the cloud so I can access my apps from the world while having all traffic into my house be through a VPN.
The VM's IPs are 192.168.1.50 ("server") and 192.168.1.51 ("client"). They can see everything on their subnet and everything on their subnet can see them.
Everything is using my router for DNS, and my router points
myapp.mydomain.comandwhoami.mydomain.comto “client”. And by "everything" I mean all computers on the subnet and all containers in this project.Both VMs and my laptop resolve
myapp.mydomain.comandwhoami.mydomain.comto 192.168.1.51, which is "client", and can ping it.Is the browser also using the LAN router for DNS? Some browsers are set to use DoT or DoH for DNS, which would mean they'd bypass your router DNS.
Do you also get "Internal Server Error" if you make the request with curl on the CLI on the laptop?
How did you check that mydomain is being resolved correctly on the laptop?
What do you get with curl from the other VM, or from the router, or from the host machine of the VM?
This seems like an issue where the wireguard is not using the correct DNS server. Does the wireguard DNS setting point to the router?
A diagrams might help me to see what is going on more clearly.

Both wireguard containers are using my router for DNS, and my router points
myapp.mydomain.comandwhoami.mydomain.comto "client".
500 errors typically log a stack trace in the server logs. Have you checked there? That would give more indication of where to start debugging.
By "server log", do you mean traefik's log? If so, this is the only thing I could find (and I don't know what it means): https://lemmy.d.thewooskeys.com/comment/514711
No. Traefik says the 500 error came from downstream. So that means either wireguard or myapp. Check the logs for those.
Just a few thoughts:
- Did you enable access logs in Traefik as well as setting global log level to debug? This usually gives a lot more info about whats going on
- Are the containers using the same docker network or host network, so they can reach each other?

Both traefik containers (on the "server" and "client" VMs) and the wireguard server container were built with
TRAEFIK_NETWORK_MODE=host. The VMs can ping each other and the Wireguard containers can ping each other.Both traefik containers were built with
TRAEFIK_LOG_LEVEL=warnbut I changed them both toTRAEFIK_LOG_LEVEL=infojust now. There's a tad more info in the logs, but nothing that seems pertinent.
I should add that I'm running Traefik 2.11.2 and wireguard from the Linuxserver image
lscr.io/linuxserver/wireguardversion v1.0.20210914-ls22.@[email protected], @[email protected], and @[email protected],
THanks for your help. My main issue ended up being that I was trying to use Let's Encrypt's staging mode, but since staging certs are self-signed, Traefik was not accepting the requests. Also, though I had to switch Traefik's logging level to Info instead of error to see that.
