Fixed API Connection Issue
Changed the Nginx proxy configuration from proxy_pass http://localhost:5000; to proxy_pass http://127.0.0.1:5000; in the container's configuration
This resolved the "ERR_CONNECTION_REFUSED" error by ensuring proper communication between Nginx and the Flask backend within the Docker container
Fixed Database Serialization Error
Updated the Python imports in app.py to properly include the date class: from datetime import datetime, timedelta, date
Modified the type checking code to correctly identify date objects: isinstance(value, (datetime, date))
This resolved the "isinstance() arg 2 must be a type or tuple of types" error that was preventing the application from retrieving warranty data
These changes resolved the connection issues between frontend and backend components, allowing the application to successfully add and display warranty information.
