Trying to use nginx (acme-companion) instead of Caddy

Added a comment to this issue but as it was closed maybe nobody read it.

I also have the same problem. All my other stacks are working with this config but searxng gives me an error. My docker-compose file:

 version: '3.7'

services:

  redis:
    container_name: redisng
    image: "redis:alpine"
    command: redis-server --save "" --appendonly "no"
    networks:
      - searxng
    tmpfs:
      - /var/lib/redis
    cap_drop:
      - ALL
    cap_add:

      - SETUID

  searxng:

      - searxng

Part of the log (too long to quote all of it)

As said all my other stacks work with this config, not sure what I'm missing here...
