Internal Server Error when I try to use HTTPS protocol for traefik backend

My setup is ELB --https--> traefik --https--> service

I get back a 500 Internal Server Error from traefik on every request. It doesn't appear the request ever makes it to the service. The service is running Apache with access logging and I see no incoming requests logged. I am able to curl the service directly and receive an expected response. Both traefik and the service are running in Docker containers. I am also able to use port 80 all the way through with success, and I can use https to traefik and port 80 to the service. I get an error from apache, but it does go all the way through.

traefik.toml

logLevel = "DEBUG"
RootCAs = [ "/etc/certs/ca.pem" ]
#InsecureSkipVerify = true
defaultEntryPoints = ["https"]

[entryPoints]
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      certFile = "/etc/certs/cert.pem"
      keyFile = "/etc/certs/key.pem"
  [entryPoints.http]
  address = ":80"

[web]
address = ":8080"

[traefikLog]

[accessLog]

[consulCatalog]
endpoint = "127.0.0.1:8500"
domain = "consul.localhost"
exposedByDefault = false
prefix = "traefik"

The tags used for the consul service:

"traefik.enable=true",
"traefik.protocol=https",
"traefik.frontend.passHostHeader=true",
"traefik.frontend.redirect.entryPoint=https",
"traefik.frontend.entryPoints=https",
"traefik.frontend.rule=Host:hostname"

The debug output from traefik for each request:

assume "hostname" is the correct host name. Any assistance is appreciated.

I think your problem come from "traefik.protocol=https", remove this tag.

Also you can remove traefik.frontend.entryPoints=https because it's useless: this tag create a redirection to https entrypoint but your frontend is already on the https entry point ("traefik.frontend.entryPoints=https")
