    It seems the issue with the compose file. Can you double check your compose file to ensure that it is as per the specifications.

    Based on my reading, I saw users getting this error when they are using ports other than 80 and 443 in the YAML file. I recommend you to review your Compose file based on the following guidelines

    Hope this helps
