Internal server error on pretix small-scale deployment via docker

[akolaarthurali]

i deployed pretix just two days ago via a small-scale deployment via docker. I got this error at the very end of the installation.I need your help on how to resolve it. I have tried my very best, but I felt i need expert help. How can I really go about this. I was testing before I make a full-scale deployment

pretix is unable to reach the PostgreSQL container at 172.17.0.1. Is PostgreSQL running and listening on that IP?

Thank you, it worked well. However it was after many hours of diligently learning how to access files and network interfaces in docker. I could have been lucky at the end.
