Touch VPN is a free application which very light and simple to use. One can download it from Microsoft Store and install it.
Problem: I downloaded it from Microsoft Store and installed it on my Windows 10 Enterprise PC. But unfortunately it was giving me pop up message ‘Unable to connect…” every time I tried it.
So next I tried the following fixes:
Checked SSL and TLS are enabled or not : Open Internet Options > Advanced tab > Scroll down under Security. In my case they were checked except Use SSL 3.0, so I checked the box against that.
Findings: Nothing changed.
Reset Touch VPN: Open Settings > Apps > Touch VPN > Advanced options > Reset
Findings: Nothing changed.
Open Device Manager > Select Mini Wan Ports > Uninstalled them > Reboot
Again tried and again failed.
Uninstall Touch VPN and visit https://touchvpn.net/
Click Get Touch VPN
Select Windows msi
Downloaded and installed.
Findings: Everything perfect …connected with a brisk.
