Chrome Extension for VPN blocked by FortiGate 201F with Firmware v7.4.5 build2702

Chrome Extension for VPN blocked by FortiGate 60E with FortiOS 5.6.2
We are running a Fortigate 201-F with firmware v7.4.5 build2702 We have a user that occasionally needs to use a VPN (1clickvpn.com). We would prefer to use a Chrome Extension that allows turning the VPN access on/off easily. We have tried different extensions but they seem to be unable to get through the firewall. Oddly, if you use a standalone VPN application instead of a Chrome Extension, it works.

Is there something in the application or security policies on the Fortigate that would prevent a VPN via a Chrome Extension?

Hello bkarankar,
Does it work if you remove the UTMs from the Fortigate Policy?
I would check the Application control Logs and see which Application is blocking these extensions. 
Mostly it will be in Proxy. 

If you do not find the signatures then you can also use the custom Signatures:

But First Narrow down to the UTM which is blocking the extension.
Remove UTMs one by One and keep trying again. 

Do not forget to use the Incognito Mode to clear cache.
