Hey guys!

I’m trying to try out the application using thedocker-compose file for development, located in [https://github.com/Tiledesk/tiledesk/tree/master/docker-compose/dev](https://github.com/Tiledesk/tiledesk/tree/master/docker-compose/dev).

All containers are initialized and stand.

However, when accessing the page localhost:8081 and trying to login with the credentials provided in the tutorial ([admin@tiledesk.com](mailto:admin@tiledesk.com) / adminadmin) I get the following error:  
\*Sorry, there was an error connecting to the server"

The browser console reports the following errors:

I believe this docker-compose-dev.yml needs some tweaking or am I doing something wrong?
