We are seeing some failures every now and then in our notarization TeamCity job where the "altool --notarization-info" command is failing with exit code 239. I didn't find anything about this by googling, except that the Mozilla guys are seeing the same issue (https://bugzilla.mozilla.org/show_bug.cgi?id=1562412).
What does exit code 239 mean and can we prevent it somehow?
