FILE section fails with 'Internal Server Error' for Proxmox












0















a question was asked on the traefik github issues a year ago and closed (seemingly without correctly following up here as suggested by the mod). I am not the OP from github, but I'm using traefik now and encountering the same exact issue.



I'm running traefik from Docker and it routes all the containers with a wildcard LE certificate. The Docker machine is a VM on a Proxmox node and I'd like to be able to "reverse proxy" proxmox the way I use to when I used nginx.



Whenever I browse to the desired frontend https://lab.my.domain I receive a white page stating "Internal Server Error" and in the chrome console it seems as though it's a 500 error.



My system is running:



Traefik v1.7.4

      a question was asked on the traefik github issues a year ago and closed (seemingly without correctly following up here as suggested by the mod). I am not the OP from github, but I'm using traefik now and encountering the same exact issue.



      I'm running traefik from Docker and it routes all the containers with a wildcard LE certificate. The Docker machine is a VM on a Proxmox node and I'd like to be able to "reverse proxy" proxmox the way I use to when I used nginx.



      Whenever I browse to the desired frontend https://lab.my.domain I receive a white page stating "Internal Server Error" and in the chrome console it seems as though it's a 500 error.



      My system is running:
