如何在Android / IOS上将TIdTCPClient连接到TIdTCPServer？

Question

Indy TIdTCPClient Error: socket error # 113 no rout to host when connecting from Android to PC.

Hello, i know i asked a lot of questions about Indy Components lately, but i'm having a real problem trying to connect TIdTCPClient in my Android device to TIdTCPServer which is on my PC Windows 10.

I have to add that i am using WIFI on LAN network, also all devices have WIFI access.

Also, i have to mention that my windows 10 FireWall is Off , so it cannot be firewalled somehow. In addition, there's no antiviruses active in my windows 10 platform, not even MCAfee .

This is the error i get when i try to connect from my Android to PC :

socket error # 113 no route to host

Note: I can connect when i use both sides TIdTCPClient and TIdTCPServer on same Machine .

Connection Template:

This is my problem:

1- Connect from PC1 to PC2 = " Failed ".

2- Connect from PC1 to PC1 = " Success ".

3- Connect from PC1 to Android/IOS = " Failed ".

4- Connect from Android/IOS to PC1 = " Failed ".

On Failed i get the error above.

看起来像是我的WIFI路由器中的问题，因为当我更换为另一个路由器时，它工作正常，无论如何，感谢您的帮助
