8.3 cannot contact other host using TLS
- 
 Three standalone servers (no pool) running XCP-NG 8.3 in the same LAN: everything ok After upgrade to 8.3 Final (on DELL R820 & R520 I had to use bios method instead of UEFI) 
 all VMs run smoothly but cannot use Live Migration anymore (that was possible on 8.3 Beta).I tried to de-activate TLS on every host without success. Finally, Live Migration works again via XOA after updating XOA to the latest. XCP-NG Center still works with 8.3 final but cannot do LIve Migration now. 
 I know that it is deprecated but it allows to see easily more than one item in the same screen.
