Network Problems with Version 25.3

Alfred_01

We have Network troubles with two of our F-Secure Installations after they update to 25.3

The first blocks an Fingerprint Sensor operating over network
The second blocks the communication between a Software running on multiple PCs

It worked before the Update, and not even disabling every setting in the F-Secure App makes it work. The only solution i found is deinstalling F-Secure completly and change to an alternative product.

disabling the Windows Firewall doesnt help either
