Dockerized .NET8 API not accessible.
When I try curl I get "(56) Recv Failure. Connection refused by peer." Docker compose

What I already tried: - Running it outside Docker, it works. - Running curl commands inside Docker, they work. - Made sure that my app listens to port 8080. - Changing port from 5282 to 8080. Port 5282 now gets failure 7, 8080 now gets error 56 similarly to what 5282 was getting. "Recv failure. Connection refused by peer." - Researched online, from what I understand this issue is .NET8 specific and has to do with "Kestrel" not allowing traffic from outside of local device. I am just using the weatherforecast template, so I have not written any code yet. I am on MacOS Sonoma 14.5 if that helps.
