Troubleshooting Database Connectivity Issue for a Mobile Application

I am currently developing a mobile application using Visual Studio 2022 and have encountered a challenge with a specific functionality. The application is designed to interact with a MySQL database, particularly to send data to this database when a user interacts with a certain feature within the app (such as a 'submit' button). Issue: The main issue I am facing is that the app is unable to successfully post data to the MySQL database. Every time the relevant button is clicked within the app, it results in an error message indicating a failure to connect to the specified MySQL hosts. This issue occurs during testing with an Android emulator. What I Need: I am looking for an experienced developer who can assist in diagnosing and resolving this database connectivity issue. The ideal freelancer should have a strong background in: Mobile application development using Visual Studio 2022. Working with MySQL databases and understanding of remote database connectivity. Experience in troubleshooting and fixing connection issues between mobile applications and databases. Project Objective: The primary goal is to ensure that the app can reliably and securely transmit data to the MySQL database upon user interaction, without any errors or connectivity issues. Note: Details about the app's specific functionality and its overall purpose will be shared privately with the selected freelancer to protect the confidentiality of the project. If you have the expertise in this area and can assist in this matter, I'd appreciate your proposal on how you would approach solving this issue.
