"Sorry, something went wrong" with Sign Up on DigitalOcean hosted docker droplet

The error seems to be happening in the compreface-ui when I attempt to Sign Up after running the installation process.

The first series of errors I think is occurring before I attempt to register. I have replaced my ip address below for privacy reasons.

Why is the code attempting to call the ip addresses 151.210.164.7 and 172.20.0.4. 172.20.0.4 is the IP address of the docker container for compreface-fe (compreface-ui). I can't figure out which contained the 151.210.164.7 IP address belongs to.

The error below appears several times "connect() failed (111: Connection refused) while connecting to upstream, client..."

And when I click on Sign Up these are the errors produced.

**To Reproduce**
Steps to reproduce the behavior:
1.) Create a new droplet on DigitalOcean with Docker 19.03.12 on Ubuntu 20.4 (there is a pre-existing install). This also installed Docker Compose by default.
2.) Download CompreFace_1.1.0.zip archive or run:
wget -q -O tmp.zip 'https://github.com/exadel-inc/CompreFace/releases/download/v1.1.0/CompreFace_1.1.0.zip' && unzip tmp.zip && rm tmp.zip
3.) To start CompreFace run:
docker-compose up -d
4.) Open in your browser: http://:8000/login
5.) Click on Create an account
6.) Enter your details and click Sign Up

Despite nothing being run on the droplet, without any calls to compreface the droplet still runs at CPU 100% every 5 minutes.
