Cloudflare setup with freenom .tk adress


I followed the cloudflare setup with a freenom .tk domain like is explained here:

However , since i moved away from duckdns, to this cloudflare setup, my google assistant integration doesnt work anymore
I just realized i had to change the fulfillment url…
But when i do, google keeps sysing it cant synchronize devices.

Does google assistant work with cloudflare setup like above with a .tk freenom domain?
Anyone got that working?
