Thank you for wisdom. We could certainly get a timeout result.

However, we would like to determine the cause if possible. The code on the receiving end of the cURL just returns the simplest json and we are able to get it to work on the server. Is the server started by artisan unable to perform new process generation?

Have you tried using postman/insomnia prior to http:get(), just as a general attempt? Maybe the port is already occupied at the time you send the request?

Thank you very much. We were able to figure out the cause of the problem.

1. When we tried to access port 8000 again while processing on port 8000, it was occupied.
2. When the port was occupied, the program did not stop because the ARTISAN side was waiting for the result forever.

And the solution was follows Start on port 8000 and port 8001, open one in a browser and use the other as a destination for cURL.

thank you both for your time.
