still not working when I use it in Docker doployed on a server and access the url by ip and port.

FROM python:3.11-alpine

WORKDIR /app
COPY ./config.json .

# Install Node.js and npm
RUN apk add --no-cache nodejs npm

RUN pip3 install --break-system-packages mcpo uv

EXPOSE 8100

CMD uvx mcpo --host 0.0.0.0 --port 8100 --cors-allow-origins "*" --config /app/config.json
