404 Not found - Path-based Routing

Traefik Traefik v2 (latest)

I have the below simple deployment that I'm unable to get to work when using Path-based Routing.

When I visit dev.mydomain.com/vote, I always hit 404 Not Found

I have also tried the official example found here to no avail. Any idea what am I doing wrong?

Hi @demi,
Thanks for your interest in Traefik.

Usually, 404 Not Found occurs when there is a routing configuration issue.
Could you provide your Traefik deployment and services ?

Also, I would recommend you to use the latest version (v2.8) as v1.x are not supported anymore.

Thanks,
Maxence

Regarding the version, yes, 2.8 is the version I'm currently using. Thank you for the note.
