Why dont you establish a Tunnel Between Sangfor to Sangfor ? and after that just route your subnets to both ends over GRE.

Secondly, please check both mikrotik are pingable?
Third, you can check the logs on sangfor when initiating a GRE Session. you can easily trace the issue from logs or share the logs here.

Are you establishing a tunnel between Mikrotik and Sangfor NGAF? If you are sure with your NGAF configuration maybe you are missing some configs with your Mikrotek device.
Is this answer helpful?

why not you make a tunnel between both sangfor NGAF and just route your local subnets of both ends.

Well, if you want to make a tunnel between both mikrotiks you need establish ping connectivity between both mikrotik then you need to open VPN ports on sangfor NGAF. finally you need to publish your local subnets towards both ends.
