[SSL Refresh Thread] Looks like there no ssl certificates, Sleeping until there's one

[fer-marino]

hi,
I'm getting this error while trying to use this container. I don't really need ssl at the moment but my understanding is that it is automatically generated anyway so there shouldn't be any problem.

I'm using docker compose, and the section related to this container is the following:
` nginx-proxy:

image: nginxproxy/nginx-proxy

image: mesudip/nginx-proxy
container_name: nginx-proxy
restart: always
networks:
  - monitoring
ports:
  - "80:80"
  - "443:443"
volumes:
  - /var/run/docker.sock:/var/run/docker.sock:ro
environment:
 - DEFAULT_HOST=opf-sv
 - PROXY_DEFAULT_SERVER=true
depends_on:
  - loki
  - grafana`

while these are the logs I have for the nginx container:

Hi @fer-marino

[Won't work] This is your current configuration

service1:
  VIRTUAL_HOST: http://opf-sv -> :3000
service2:
  VIRTUAL_HOST: ws://opf-sv -> :3100  # this own't work

As of now nginx-proxy doesn't support having conditional websocket and http on same path.

Alternative approach

If its possible a different path is advisable like this

service1:
  VIRTUAL_HOST: http://opf-sv -> :3000
service2:
  VIRTUAL_HOST: ws://opf-sv/ws -> :3100/

@fer-marino Yeh I agree. It's good idea to generate dh-parameter only when required.
