[SMTP] An attempt to connect gmail failed - Only when using VPN or inside the work network

I hope someone else had received this error, only when using VPN or accessing from the work network. When I am using my home wifi, without VPN there is no error. It;s obvious, my VPN and office network is blocking. What can I do to prevent this error or bypass my VPN or office network settings.
Please help!!

Hello Tathagat,
if the problem is with your work network, you should probably consult your IT personnel about fixing the setup of the network or making an exception for eM Client. Unfortunately eM Client itself cannot bypass this.
