Solution 1:[1]
I also had this problem. In my case, I was trying to connect my Android app with node REST api which was running on port 3000. I also had this connection timeout problem. My OS is windows.
Folow these steps.
1)- Check whether the mobile and Computer are connected to same network
2)-Check the computer IP assigned by router using below comand on cmd
ipconfig
The result will be like this
Windows IP Configuration
Wireless LAN adapter Wi-Fi:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : ********
IPv4 Address. . . . . . . . . . . : ********
Subnet Mask . . . . . . . . . . . : ********
Default Gateway . . . . . . . . . : ********
***.***.8.1
Then check the used IP address. It must be IPv4 Address of the connected wifi network
3)-Set the network as private/ Home network
On windoes 10, you can do this by select taskbar wifi icon ==> selecte the properties of connected network ==> Under Network profile set the network as private
4)-Check the Firewall is disabled.
If your firewall is enabled please turn off it until test finish and remember to turn on it again after finishing your task

This issue can occur due to FIREWALL, please check below steps to resolve it
- Check whether you can connect directly through URL, using any of browser instead of Android app.
- If it fails, then it could be an issue with network connectivity not with android code.
- One of reason behind Network connection failure is "FIREWALL" option, which might be blocking connection request.
- In case of MAC machine, open "System Preferences==>Security & Privacy ==> Firewall ==> Turn Off Firewall". It will turn of FIREWALL on system.
- In case of other OS, please turn off FIREWALL with respective settings.
Now you should be able to connect through code as well direct through browser, hence there won't be any "SocketTimeoutException" error. Good Luck.

The issue was resolved when my phone was connected to the local server wifi in which the webservices were hosted.
Solution 4:[4]
If you are using an emulator in android studio, and have never accessed the network through it, then try launching the browser and accepting the agreement.
Solution 5:[5]
for window user
type ipconfig in your cmd find out the ipv4 IP address, it is your post URL IP address then find out the port number and disable your network firework
done
Solution 6:[6]
My android phone had AnonyTun (vpn app) connected. Disconnecting was the solution.
Solution 7:[7]
Sometimes if your system from where you are trying to start Metro bundler is connected to VPN will cause such errors.
