Server 2.3.1 and template generator

Hello,
I am using flash templates with Server v2.0.7.
With animate cc 2017, the template generator works without any problems.

but I want to use server v2.3.1
flash template still works.
but template generator does not connect to caspar server.

for server v2.3.1
How can I use the animate template generator?

Best Regards,
Murat
