Apache guacamole addprefix Broken

Traefik Traefik v2
1

I upgraded from 2.8.1 to 2.8.3 latest and my addprefix-guacamole middleware stopped working. it now goes to the tomcat "it works" landing page and when i add "/guacamole" to the url I get a 404 error. Have both my pihole machines set up with the addprefix-pihole and they are still working fine.

Was wondering if anyone has had this issue? with the latest update of traefik there was a change on how traefik reads configs with errors, noted here on git . I had a few and corrected but still no dice on guacamole working, any help will be very welcomed

using the traefik config.yml here is my config.yml
