Error response from daemon, wait until the container is running

I follow the instruction. I changed domains and mail in init-letsencrypt.sh and app.conf. When I run ./init-letsencrypt.sh, I get error:

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: kosyachniy.com

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.

### Reloading nginx ...

How can I fix it?

Happened to me, I had not changed the domain properly, so the path to the certificated was invalid, preventing nginx from starting

I'm not sure if this is your issue, but I was running into the same issue. In init-letsencrypt.sh I removed the -d from the docker-compose command that starts nginx after creating the dummy certificate so I could see any logs and sure enough it was complaining about the dummy certificate and it said something like "ee key too small" and nginx wouldn't start.

I fixed it by changing rsa:1024 to rsa:2048 in the openssl command (then re-adding the -d I had removed) and then everything worked.
