Filemaker Server 19 SSL help.

[emtau]

Greetings, I've installed Filemaker Server 19 on a separate Windows 11 PC, I hosted my Filemaker Solution on it but I am having difficulties accessing it from Filemaker Pro 19 client on a different PC (same network). The Filemaker solution was originally Shared without a Server and I can access it without a problem.

During Filemaker Server installation and configuration it asked for a custom SSL certificate but since I don't have one I just go with the built it Filemaker custom SSL (for test purposes). I am not sure but that doesn't seem to work to connect with Filemaker Clients.

How can I get a free SSL and how to install/configure it properly?

Thanks.
