What is the full error

Exactly what is your setup: Is Windows 10 used to host the Firebird
server, or is Windows 10 used on the client machines (or both)? Are you
using Firebird Embedded, connecting locally, or over the network. Is
Firebird running as a service, if so under what user? What happens if
you run it as an application (firebird -a from the command prompt with
Firebird 3).

Have you verified the Firebird process is actually running, and is
listening on port 3050 (eg check in command prompt with netstat -ano).
Have you verified the Windows 10 firewall settings?

Did you also update the Firebird client install on the client machines?
