*** Sorry i am not good at english ***
I have analyzed this issue.
I found that this problem was caused by (Protocals TLS Version).
Data running through the App requires (TLS version 1.0 / 1.1 / 1.2).
You can come here to solve problems as follows.
#Registry Editor [Adding TLS Version 1.0/1.1/1.2]
1. Open NotePad
2. Pate Data
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client]
"DisabledByDefault"=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1]
