    I am running the 3CX Client (version 15.5.10795.4) on a Windows 10 computer, and in Configure Accounts -> Advanced Settings I have it set to use TLS and Only Secure. With those settings the client registers to the server (running version 15.5.10244.4) fine so that tells me the certificate should be setup correctly; however, in group policy under Computer Configuration -> Policies -> Windows Settings -> Security Settings -> Local Policies -> Security Options if I enable "System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing and signing algorithms" the 3CX client fails to register to the server.
