Dear all
I just installed a new Debian 9.5 server and Alfresco 6.2 based on the docker compose template from github:
https://github.com/Alfresco/alfresco-docker-installer
all by the book, according to the above instructions
In the server root I made a directory /docker-compose and from there I run 'yo alfresco-docker-installer'
All good - I have now the start.sh script - no errors 
After I run the start.sh script and the container is created ( or restarted ) I have an error :
Creating docker-compose_proxy_1 ... done
Waiting for alfresco to boot ...
waiting for 1 resources: http://localhost:80/alfresco/

wait-on(29184) Timed out waiting for: http://localhost:80/alfresco/; exiting with error
Error: Timed out waiting for: http://localhost:80/alfresco/
I'm able to access http default login page (!) on the ip directly or on http://Ip/share but I'm unable to login using default admin/admin credentials
On the main page is telling me that I have input wrong credentials and in the /share page is warning me about "Your authentication details haven't been recognized or Alfresco Content Services may not be available at this time."
The alfresco-doker-installer options are :
Version 6.2, 8GB, no mariadb, multiple languages, no smtp, no ldap, no ftp, port 80, no https, no windows, startup script
No matter which combination of the above ones works - not 6.1, https, wiht ldap, etc - same problem, same errors when I start the container
Any ideeas ? Many thanks
