Connection Issue with Flask/Selenium

Hello dear Railway community, I am currently facing an issue when trying to connect to the server that my project is deployed into, it is a Flask application that works when ran through a Docker image (Docker Desktop), however I have trouble accessing it through railway. It might be due to the docker run map porting command, that I haven't figured how to implement on Railway yet: Docker file; ARG PORT=443 FROM cypress/browsers:latest RUN apt-get install python3 -y RUN echo $(python3 -m site --user-base) COPY requirements.txt . ENV PATH /home/root/.local/bin:${PATH} RUN apt-get update && apt-get install -y python3-pip && pip install -r requirements.txt COPY . . CMD uvicorn main:app --host 0.0.0.0 --port $PORT Thanks in advance for your kind help
