Unrecognized vehicle network toolbox function in standalone executable

Hello everyone,
For the purpose of evaluating measurement data I have written a program which imports and processes Vector's Measurement Data Format (*.mdf, *.mf4). To acomplish this, I make use of the functions "mdf" and "read" as in the following example:
LogFile = mdf(fullfile(PathName,WorkFile));
TT = read(LogFile,ChannelNumber,ChannelNames);
This works just like a charm in Matlab execution and even in the standalone application I built with the Matlab Compiler. Even for other users who do not own the Vehicle Network Toolbox (which is required for both functions mentioned above).
But for some reason - very unclear to me - this standalone application stops working as soon as the colleagues try to use this version from outside of the company network. Since homeoffice is still a major thing these days I was hoping the app would do the work as usual but instead there is the following error:
So I thought the function from the toolbox obviously cannot be found and therefore has not been compiled. So I added the function pragma:
%#function mdf
which did not change a thing at all.
And now I'm quite confused how the use of the standalone app differs from the different locations inside the company. Even though the colleague is using VPN to connect to the Matlab license server of the company in the first place.
Is there any reason for this somewhat strange behaviour?
Thanks a lot in advance,
Benjamin Frank
