I had the same issue. Came here to ask for more attention to this issue. But then I noticed a typo in my config.

In any case, to fix this issue you also need to strip the /octoprint prefix and add the X-Scheme header if you're using https. I'll add this to the community FAQ as well.

labels:
  - "traefik.http.middlewares.octoprint-headers.headers.customrequestheaders.X-Script-Name=/octoprint"
  - "traefik.http.middlewares.octoprint-headers.headers.customrequestheaders.X-Scheme=https"
  - "traefik.http.middlewares.octoprint-strip-prefix.stripprefix.prefixes=/octoprint"
  - "traefik.http.routers.octoprint.middlewares=octoprint-headers,octoprint-strip-prefix"

I have the same bug when I try to use it with the Path Prefix, is there a solution for it yet?

Try:

labels:
  - "traefik.http.middlewares.octoprint-headers.headers.customrequestheaders.X-Script-Name=/octoprint"
  - "traefik.http.middlewares.octoprint-headers.headers.customrequestheaders.X-Scheme=https"
  - "traefik.http.middlewares.octoprint-strip-prefix.stripprefix.prefixes=/octoprint"
  - "traefik.http.routers.octoprint.middlewares=octoprint-headers,octoprint-strip-prefix"
