Running .net application on ec2 windows instance

I have a .net windows application (exe) which I would like to run on my windows ec2 instance.

I can run it on my computer at home but it doesnt even load (no error or any message) when I try to run it.

The application connects to a remote api and database. (it has no publisher credentials)

I am new to this. What are the general /most common settings I am missing here to get it to work? Both aws and windows firewall settings for example.
