Error accessing proxy from traefik

[lonix1]

I'm using this with traefik and it works like a charm.

...Except when it doesn't. For example, when I must update services, and then restart traefik. Then traefik restarts without error, and the container becomes "healthy". But requests to services time out.

I thought it was a traefik problem. Then I checked the logs, and every time I have this issue I see something like this:

time="2023-07-17T07:44:45+03:00" level=error msg="Provider connection error error during connect: Get "http://tecnativa:2375/v1.24/version\": dial tcp: lookup tecnativa on 127.0.0.11:53: no
such host, retrying in 9.503388201s" providerName=docker

The "no such host" part is incorrect, because the tecnativa container is working, and reported as "healthy". I wonder what that v1.24 is?

The only solution is to restart both traefik and tecnativa (and sometimes other services which are served by traefik!)

I am using the most recent official tecnativa release 0.1.1. And docker 24.0.4 on debian.

Any ideas?
