Troubleshooting installation errors

Common installation errors

[::]:3030 failed (97: Address family not supported by protocol...

When installing or starting the server, you might encounter an error related to Nginx, as shown below:

1#1: socket() [::]:3030 failed (97: Address family not supported by protocol)
socket() [::]:3030 failed (97: Address family not supported by protocol)

This error indicates a problem with Nginx attempting to open a socket on an IPv6 address, which might not be supported in your network configuration.

Solution

1. Open UI Bakery .env (Updating UI Bakery ENV variables guide)

2. Add or update the following line:

UI_BAKERY_LISTEN_IP6=false

1. Save the file and restart UI Bakery

docker compose down
docker compose up -d

Escaping special characters

Sometimes when using special characters in your environment variables, like &, $, %, the variables may not be escaped properly. To fix it, put the variable value in quotes like this:

UI_BAKERY_SMTP_PASSWORD='myPasswordWithSpecicalChars$33%#4'

If you have an older version of Docker installed, you may need to use double quotes instead.
