I am trying to work with traefik middlewares but none of the traefik middleware is working for deployed service following is the docker-compose file and toml file. I am initializing traefik with a toml file Can someone spot any error?

You are using a mix of Traefik v1 and Traefik v2 configuration.
traefik.frontend.rule -> Traefik v1
traefik.http.middlewares.test-replacepath.replacepath.path -> Traefik v2
Traefik v1 and Traefik v2 configuration are not compatible.

im running a gitlab-ee docker container behind a traefik v1 docker container. My gitlab is supposed to run on the domain gitlab.dev.example.com:65443 the port 65443 is being forwarded to 443 on my server within my router (i have other stuff running on my 443 and 80 port). my traefik dashboard is running on traefik.dev.example.com:65443/dashboard/
Now when i want to get a lets encrypt certificate with traefik it tries to get it for the domain gitlab.dev.example.com and fails with "Unable to obtain ACME certificate for domains "gitlab.dev.example.com" [...]"
if i visit https://gitlab.dev.example.com:65443 it opens my gitlab container but with the "Traefik Default Cert". I cannot push or pull from these gitlab repositories because the SSL Certificates are self signed hence why i want to get a lets encrypt one.
i swapped out the actual domain with "example.com" obviously
my traefik.toml:
debug = false
logLevel = "ERROR"
defaultEntryPoints = ["https", "http"]
[web]
address = ":80"
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "traefik.dev.example.com" //swapped the url out
watch = true
exposedByDefault = false

I'm new to SSL certificates with Traefik and have been having real trouble getting a successful deployment.
I have a server and domain that I have deployed my application on using Traefik and Http without issue. I would now like to deploy the same application, running on port 9000, to be deployed in Https using LetsEncrypt following the Traefik docs . I can verify that the certificate has been properly created using an SSL checker, however, when I try to visit the site I get Internal Server Error. There are no errors reported in either of the docker logs and I cannot figure out what to try next.

Finally was able to find a workable solution for this. I may have just been using old information but the best reference to host an application with Traefik on Https using LetsEncrypt was found here.
The working Yaml example is below. Using this example will also eliminate the need for a Toml file!

I am new to traefik and am trying to set up my containers to be reverse-proxied by traefik at the moment. It all worked fine while using traefik.frontend.rule=Host:grafana01.mydomain.com for routing requests to grafana01.mydomain.com, but due to infrastructural issues within our network I'd rather use traefik.frontend.rule=Path:/grafana01/ to redirect to mydomain.com/grafana01. Yet for some reason it does not work.
My traefik.toml file as well as my two docker-compose.yml files for traefik and grafana, respectively:
#Traefik Global Configuration

I'd appreciate any help!
Changing traefik.frontend.rule=Path:/grafana01/ to
traefik.frontend.rule=PathPrefixStrip:/grafana01 as well as adding
GF_SERVER_ROOT_URL=%(protocol)s://%(domain)s/grafana01
did the trick for me.
I'm setting up a gitlab server behind traefik proxy, but my gitlab sshd logs says traefik send http request over 22 port to gitlab, causing Internal server error.

I found there is a similar discuss here, however the answer did not work, is there any way to change gitlab backend from 22 to 80?

Looks like you have a typo in your gitlab docker-compose.yaml file.
Replace traefik.prot by traefik.port and it should work better.
I have docker compose with nginx running with the following config:

and traefik in docker-compose with the following config:
version: '3'
services:
reverse-proxy:
image: traefik:alpine
command: --api --docker
ports:
- "80:80" # The HTTP port
- "8080:8080" # The Web UI (enabled by --api)
volumes:
- /var/run/docker.sock:/var/run/docker.sock # So that Traefik can listen to the Docker events
- ./traefik.toml:/etc/traefik/traefik.toml
the traefik.toml is kept basic and looks like this
defaultEntryPoints = ["http"]
[entryPoints]
[entryPoints.http]
address = ":80"
The Web UI shows the following
When calling my domain www.example.com I get a timeout.
Add the following in your traefik.toml

endpoint = "unix:///var/run/docker.sock"
watch = true

You need to put both container on same network.
Create a docker network inside your host machine. docker network create {network name}.
In your docker-compose use the existing network that you created to connect both containers. You can read https://docs.docker.com/compose/networking/#use-a-pre-existing-network on how to use it.
Add each service to the above network.
