Hi! I’m trying to run the CC6 Yocto build for the first time (bitbake dey-image-qt), however it fails when trying to fetch ftp://ftp1.digi.com/support/digiembeddedyocto/source/mca\_tool-1.15-arm.tar.gz Looking at the directory, ftp://ftp1.digi.com/support/digiembeddedyocto/source/, using a browser the file is present. But if I try to download it the connection is reset by the server. I can’t download any of the files in that folder to be exact. I’ve tried to download it separately on two different computers with chrome, firefox and curl, but the result is the same. Does anyone have any suggestions on how to proceed? Thanks! ---

i just tried it and it downloads, so it must be your firewal or corporate settings. try cellular connection on your phone. ---

Yes, that worked. The firewall blocked that specific file for some reason. Thanks!
