so, it was actually an IDE thing. Running the containers using the IDE's UI would actually set the environment to development and enable Swagger, for example

Actually, I've tried to run busybox and appropriate images for fetching data inside the network, but looks like the response is the same:

As the output suggests, the container's address is 172.18.0.3, but any tool that attempts to connect externally just gets refused and fails

Docker networking docker network inspect for that docker-compose network is as follows. I just removed the MacAddress parts for security reasons:

Local machine refuses to connect to an ASP.NET Core Web API container
Source Code this is the API source code: https://github.com/trsaints/trsaints-frontend-api The api container's http port is mapping to 8082 becaues I have an apache server running on the host's 8080 port. But that shouldn't be an issue at all, as far as I know. What I've tried until then Also, I've tried the following suggestions from forum posts with related issues: * Checking iptables rules to assure the container address is not being blocked by the host's firewall: sudo iptables -L -v -n | grep 808: 
    0     0 ACCEPT     6    --  !br-233688ab8a57 br-233688ab8a57  0.0.0.0/0            172.18.0.3           tcp dpt:8080
    0     0 ACCEPT     6    --  !br-233688ab8a57 br-233688ab8a57  0.0.0.0/0            172.18.0.3           tcp dpt:8081
    0     0 ACCEPT     6    --  !br-233688ab8a57 br-233688ab8a57  0.0.0.0/0            172.18.0.3           tcp dpt:8080
    0     0 ACCEPT     6    --  !br-233688ab8a57 br-233688ab8a57  0.0.0.0/0            172.18.0.3           tcp dpt:8081
* Disabling ufw temporarily * Setting ASPNETCORE_URLS to http://+:8080/ * Adding Kestrel:EndPoints:Http:Url=http://+:8080 to docker-compose.yml * Delete the container's and its images to clear any previous data None of the options above had any effect.
