Remote laptop is not syncronyzing with MSFS2020 in EFB v2 - Support forum Posted March 25 Hi Saverio, thanks for the files. It seems that there are two problems on the Client side and one problem with the unzip, which affects both sides the Client and the Server: 1) The Client (192.168.178.49) has not the same network address as the the Server (192.168.0.103), assuming the so called subnet mask is set to 255.255.255.0. 2) The Client's datafolder ("C:\Users\saver\OneDrive\Documenti\AivlaSoft\EFB2") seems to be a cloud synchronized path. This will lead to unforeseeable problems. Synchronized folders might be good for office documents but not for data storage of a running application. 3) The Client is not capable of unzipping the airports-database which is being sent from the Server. This cause for this issue is not known because it origins in a third-party-dll which is used by EFB. With next EFB update this DLL will no longer be in use as it has been replaced now.
