Endpoint Security- Failed to create new site Reason: Site is not responding

[Theo]

Location: China

Security Gateway: Standalone/ CheckPoint 2200 Appliance/ R80.30

Problem: Unable to create site in Endpoint Security

Action: Verified and compared the settings of gateway object from other working sites with VPN Clients

Please refer to settings of my VPN Clients

I've noticed this problem recently with locations in China as well. Apparently, ISPs there have been forced by the government to block https inbound. And the VPN client first makes an https connection before moving to IPSEC. I don't know if we can change this behaviour.

As I was thinking, is there any way that Endpoint Security can connect using another port aside from 443??
