All services return 404

carlosoras · April 4, 2022, 7:08pm

Hello, first of all, thanks for your help, I'm quite new with docker and even newer with Traefik, so I'm sorry for all mistakes.

So, I was trying to install Traefik to expose some services, I just follow a tutorial and try to expose my first service, but I'm always getting a 404, even when I try to acces to dashboard.
I have a Raspberry with pihole installed, because of that I setted up port 82 in place of 80.
Also, in my router configuration, I'm routing the port 80 to my raspberry's ip, port 82, and I also redirected 443 port;

Here is my configuration, when I access to myIp:82/api I have a 404 page not found. Also if I try with my external ddns domain. and for all the services.
Also, my acme file is empty.
I tryied to enable the logs, but I'm not getting nothing in traefik.log, however in access.log I can see the querys.

docker-compose.yml

Hello @carlosoras

Can you please share the log file while Traefik is starting? Especially the first few lines are important, when Traefik is loading the configuration and stating the appropriate provider.

Thanks for your reply, so here is the logs

carlosoras · April 10, 2022, 9:58am

Well, some updates. as I saw here https://community.traefik.io/t/2-3-errors-on-container-start-is-this-someting-to-worry-about/8438/8
using yml and toml can be a source of trouble, so I rewrite my files to yml.
But still I'm having this as logs:

peterhoneder · April 11, 2022, 4:35am

Hi!

what seems to happen here, is that your connections get closed. Traefik doesn't let you know why it closed the connections, but I would guess something is trying to stop traefik. If you run it, make sure nothing tries to stop or kill the traefik process or monitor if that could happen. Also one thing you could try it to turn on debug logs.

carlosoras · April 15, 2022, 4:36pm

I'm quite new to docker so I don't know what can be stopping traefik. I don't have other containers.
Do you have any clue how I can activate debug logs??
I try adding this in my traefik.yml:

log:
  level: DEBUG

But the log is still the same.

carlosoras · April 26, 2022, 7:55pm

well, after trying again, here is my log in debug, I don't see the closed network connection anymore, but still it doesn't work, any clues??
