Unable to connect to services deployed on Remote Servers
Hello! I am running into a network issue when trying to launch services from my dokploy instance. I am using the multiple server approach and it seems like Traefik isn't able to route to the network generated for the service?
I was able to solve this...partially. I redeployed the apps on the dokploy web server instead of my remote one and it still failed so i tried "rolling" the traefik.me domain a couple times and I got a warning that I need to update my web server's IP.
Adding the server IP to my web server config fixed the locally deployed ones but the remote servers still fails. Trying to figure out how i can fix this.
VPS: Linode
OS: Ubuntu 24.04
Dokploy: v0.20.8
Dokploy is deployed on a custom subdomain. I am able to access the remote server terminal via ssh from dokploy. Container is healthy and no traefik logs.

The remote server has its own Traefik and IP instance. Are you routing to it’s IP directly?
I don't see a traefik instance running on the remote. I setup the Remote server with the external IP
do i need to make a dynamic config for the server's traefik file system?
something like this?
http:
routers:
catchall-traefik-me:
rule: HostRegexp({subdomain:.+}.traefik.me)
entryPoints:
- web
service: dokploy-service-app
services:
dokploy-service-app:
loadBalancer:
servers:
- url: http://dokploy:3000
passHostHeader: true
?
root@dashboard:/etc/dokploy/traefik/dynamic# docker ps

I also changed my dokploy.yml on my main instance to the following:
http:
routers:
dokploy-router-app:
rule: Host(<MY_CUSTOM_DOMAIN>) && PathPrefix(/)
service: dokploy-service-app

I'm new to traefik so im not sure this is correctDid you click
Setup Server?
yup yup
And the
Validate tab gives you all green?
If you have a domain, does the A record of the service you try to deploy point to the remote server?
i do have a domain for the dokploy but not for the remote server. should i set it up?
like a wildcard for traefik.me through cloudflare?
Set an A record for like
remote.example.tld pointing to the remote and check if you can reach it there. The same domain has to be assigned in the domain tab of the service of coursegotcha gotcha so i can't just use the traefik.me if dokploy is already configured with an A record?
You can probably use a traefik.me domain. Just make sure the IP in the domain is the IP of the remote server and not the IP of the Dokploy server. The routing does not go through Dokploy, but straight to the remote server
I'll give that a try then!
Make sure the remote server also does not have port 80 and 443 open in the firewall
does not??
i did open them
Does
ah gotcha 😅
just making sure
Wrote it a bit too fast there 😅
lol no worries! i had real fear. I was like how does traefik work. its real internet magic
so i added the a record and digging the domain shows the proper IP but still seeing the issue
There is no need for a record on cloudflare when using traefik.me domains. The IP of the server is present in the URL
mmm they match so im not sure
Does your Dokploy instance also use IPv6 address?
it technically does but im not using it
I couldn't find any traefik docs about IPv6 routing, and I also think Docker does not have it enabled by default
yea i was just using ipv4
Try IPv4 on the remote
i am using ipv4?
24b7ah-654ec8-69-164-205-11 part of your URL you sent is your VPS IPv6 addressahh gotcha. that is two hashes generated from dokploy (in isolated mode) followed by the ipv4 address. I'll remove the hashes
http://observability-metabase-69-164-205-11.traefik.me/
should there be a traefik container on my remote server? i don't see one
Yes it should have one
Maybe you’ll have to set it up again
i was able to resolve this by selecting the server and enabling the traefik dashboard. I think dokploy realized there was no traefik container on the remote server and spun one up. weird. I am able to route traffic to my remote server now! Thanks for all the help
It seems like you were unlucky with the setup of the remote server at last. Just unlucky I guess
