cURL issue at start

Hi, I got a script that call another service to init some var environement like this :

#!/usr/bin/env bash

if [ -z "$TOKEN_PROVIDER_ADDR" ]; then
    echo "TOKEN_PROVIDER_ADDR environment variable is not set"
    exit 1
fi

sleep 20

# API URL
PROVIDER_API_URL=$TOKEN_PROVIDER_ADDR/token/provide

echo "Fetching key from $PROVIDER_API_URL"

# Fetch the token
TOKEN=$(curl -s -v $PROVIDER_API_URL)

echo "Key: $TOKEN"

# Check if the key is retrieved successfully
if [ -z "$KEY" ]; then
    echo "Failed to fetch key from API"
    exit 1
fi

# Export the key as an environment variable
export TOKEN=$TOKEN

# Run your application
/app

#!/usr/bin/env bash

if [ -z "$TOKEN_PROVIDER_ADDR" ]; then
    echo "TOKEN_PROVIDER_ADDR environment variable is not set"
    exit 1
fi

sleep 20

# API URL
PROVIDER_API_URL=$TOKEN_PROVIDER_ADDR/token/provide

echo "Fetching key from $PROVIDER_API_URL"

# Fetch the token
TOKEN=$(curl -s -v $PROVIDER_API_URL)

echo "Key: $TOKEN"

# Check if the key is retrieved successfully
if [ -z "$KEY" ]; then
    echo "Failed to fetch key from API"
    exit 1
fi

# Export the key as an environment variable
export TOKEN=$TOKEN

# Run your application
/app

But I got this error :

I've just changed the host name by xxx for privacy purpose.

Solution:

check out this docs section https://docs.railway.app/guides/private-networking#known-configuration-requirements-for-ipv6 click the go fiber dropdown...

62a7d631-15d2-4bde-a633-b2e28b306105 Here is my final "FROM" in my Dockerfile :

FROM bash:4.1.17 AS final

# Import the user and group files from the first stage.
COPY --from=builder /user/group /user/passwd /etc/

# Import the Certificate-Authority certificates for enabling HTTPS.
COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

# Import the compiled executable from the first stage.
COPY --from=builder /app /app

# Import the start script
COPY --from=builder /usr/local/go/src/github.com/EzeXchange-API/APICore/start.sh /start.sh
RUN chmod +x /start.sh

RUN apk add --no-cache curl

# Perform any further action as an unprivileged user.
USER nobody:nobody

EXPOSE 8000

# Run the compiled binary.
ENTRYPOINT ["bash", "/start.sh"]

My Dockerfile build fine And I've activated the private networking of course

what kind of app are you trying to fetch the token from
