✓ redis is configured
✓ push server is receiving redis messages
✓ push server can load mount info from database
✓ push server can connect to the Nextcloud server
🗴 push server is not a trusted proxy, please add '127.0.0.1' to the list of trusted proxies or configure any existing reverse proxy to forward the 'x-forwarded-for' send by the push server.
  See https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/reverse_proxy_configuration.html#defining-trusted-proxies for how to set trusted proxies.
  The following trusted proxies are currently configured: "127.0.0.1"
  The following x-forwarded-for header was received by Nextcloud: 172.17.0.1
    from the following remote: 127.0.0.1

  If you're having issues getting the trusted proxy setup working, you can try bypassing any existing reverse proxy
  in your setup by setting the `NEXTCLOUD_URL` environment variable to point directly to the internal Nextcloud webserver url
  (You will still need the ip address of the push server added as trusted proxy)
