Pack installer OFFLINE

Hello everyone

We are having a network problem with the pack installer. When using company wifi we see "OFFLINE" error. If I connect my laptop to my hotspot internet I do not have any problem. 
I can ask our IT to give access to certain servers(address's).

Which address's should we give access to?

  • As Ralf already explained, the Pack Installer uses cpackget.exe also to check the online status. This command is used:

    >cpackget.exe connection
    E: "">www.keil.com/.../keil.vidx": remote server is offline or cannot be reached

    If there is no output, cpackget has a connection to the keil.com server. If you see the error message above, there is no connection to the server. Please note that this URL can be redirected/forwarded to another location. Finally, cpackget needs access to many chip vendors, because the packs are usually hosted there. Please see for more information:

    Maybe you have a mandatory proxy server in your company network. The page above explains how to tell cpackget to use the proxy server. 

  • Hello Hans,
    I was having the error you mentioned
    >cpackget.exe connection
    I: Using path: "">https://www.keil.com/pack"
    E: "">https://www.keil.com/pack": remote server is offline or cannot be reached

    After this our IT gave permission to "keil.com" and "keil.arm.com" on the firewall. It seems that our firewall was blocking it. I do not see any error when I run "cpackget.exe connection".

    But I still see "OFFLINE" error on the pack installer.
    What other permission should we give or which settings should we do?
