Hello,
2019-11-30 09:49:10 10217 [HttpClient] <-- HTTP FAILED: java.net.ConnectException: Failed to connect to /192.168.0.100:8443

There is no connection to 192.168.0.100:8443 from your Android device, so it’s probably a connectivity problem (firewall, …). Does it work when you access the URL from your Android browser?
