Certificates are not generated

Hi,

I'm trying to generate some certs all using docker using zerossl, aws and dns-01 but the certificates never seem to generate, I keep getting the following error.

These are the ENV Vars I have set on the acme-companiion container are

environment:
      - NGINX_PROXY_CONTAINER=nginx-proxy
      - DEFAULT_EMAIL=myemail@mycompany.com
      - ACME_CA_URI=https://acme.zerossl.com/v2/DV90

      - AWS_ACCESS_KEY_ID=myid
      - AWS_SECRET_ACCESS_KEY=mykey
      - AWS_REGION=my-region-1
      - DEBUG=1

and these are the ENV Vars I have set on the app Container

    environment:
      - VIRTUAL_HOST=my.domain
      - LETSENCRYPT_HOST=my.domain
      - LETSENCRYPT_EMAIL=myemail@mycompany.com

• When I use these setting with the acme.sh script on the same machine it works correctly.
• The application is working correctly as I can access via port 80.
• Even if I wait beyond the timeout the same error message appears
