What exactly is the problem? Please also specify some

You're describing it too much, specifically?
If the server is not a problem, the request can be sent, the network should be through. According to your description, this is the default for your server, and the client-to-server is not a problem.

1. Simple test, such as GET request to access a test URL, test URL just back to a word hello, see if received.
Based on this test result, further design the test.
