@ruben-arts do you have any idea how we can mitigate this? Restarting manually jobs is always doable, but annoying.

[ruben-arts]

@traversaro I don't but I'll ask @baszalmstra to take a look at it. I think we should also have a way to auto retry as issues like uploading failures do to a simple http error is very annoying if a retry to do the trick.
